Description

CORROSION BIO-INHIBITOR CONTAINING SCORPION VENOM TECHNICAL FIELD The invention is effective against iron in a hydrochloric acid (HCl) medium, unlike other known methods. with an animal-derived bio-inhibitor, which is also different from traditional corrosion inhibitors. It is related. PREVIOUS TECHNIQUE Corrosion, in short, is the process by which metallic materials interact with their environment, a process inherent in natural processes. and industrial investment and production due to the event of returning to their stable state It is one of the most significant problems that greatly affects costs. In fact, corrosion. This is an unavoidable danger that threatens almost all engineering materials, and the same The worst thing about our time is that technical malfunctions also occur. This is considered one of the problems. Corrosion causes both cost and environmental problems in the engineering industry. Considering the effects, the protection of metals and alloys in corrosive environments is also important. In fact, it has given rise to a number of useful endeavors. These efforts, potentially to delay the corrosion process and minimize the rate of corrosion that occurs during this process It aims to reduce corrosion. For this purpose, it uses products that stop or slow down corrosion formation. New and environmentally friendly biological inhibitors are needed. Various methods are used in the fight against corrosion. These methods Among them, corrosion inhibitors are the most commonly used. Their high effectiveness... And it stands out as one of the most practical methods due to its various application areas. It is emerging. Protective bioinhibitory substances generally form a film on the metal surface. They increase the resistance of the metal / solution interface by sealing it with a protective layer. Therefore, more synthetic, organic / inorganic and plant-derived biological products are used. Inhibitors are used to eliminate the harmful effects of corrosion. However, most synthetic organic compounds are expensive and pose risks to living organisms and the environment. Their use is becoming increasingly restricted due to their toxic properties. Recently, due to environmental regulations, plant extracts have been used because of their low toxicity. and advantages such as easy availability against corrosion problem It offers an alternative solution. 1 THE PURPOSE OF THE INVENTION Environmentally friendly and natural bio-inhibitors have recently become popular in preventing corrosion. Plant-derived extracts are generally used as green inhibitors against corrosion problems. They are preferred. Considering all of this, alternatives to herbal ones are considered. Animal-derived structures are also environmentally friendly, therefore corrosion bio- One of the aims of the invention is its use as an inhibitor. Based on this aim, An animal secretion that prevents the corrosion of iron in a hydrochloric acid environment. Scorpion venom, which is included in this invention, has been used as a corrosion bioinhibitor. Scorpion venom prevents the corrosion of iron in a 1.0 M HCl solution. It has been observed to be as effective as plant-based sources. DETAILED DESCRIPTION OF THE INVENTION The discovery involves an animal-derived secretion from the scorpion Leiurus abdullahbayrami. the use of the species' venom as a bio-inhibitor in preventing metallic corrosion This is relevant. In this context, the use of corrosion prevention, which is the subject of our patent application, is related to this. The bio-inhibitor developed for this purpose contains scorpion venom. In the current state of the art, it is obtained synthetically or from plant extracts. Green inhibitors, which have been widely used, are commonly preferred. However, our invention... within the scope of obtaining the scorpion venom-containing bio-inhibitor Firstly, Leiurus abdullahbayrami venom, Niğde Ömer Halisdemir University Arachnology Obtained from the Museum (NOHUAM). Obtained from the species Leiurus abdullahbayrami. 0.1733 g of poison was collected. The stock solution concentration of this poison in water is calculated as mass / volume. The actual content of the stock poison aqueous solution was calculated as 0.3466% (w / v). After the concentration is determined, the concentration is reduced from this solution by dilution method. To determine its effect on corrosion, an ideal concentration range has been determined. The concentration range is 0.020% (w / v) to 0.160% (w / v). Electrolyte medium at each concentration for conducting electrochemical experiments A 1.0 M HCl solution was used. Iron was chosen as the working electrode. Percentage composition by mass (%w) of the iron whose corrosion effect was investigated: 0.06030%Cr; 0.00222%Nb; 0.07890% Ni; 0.01100% V, 0.01100% P; 0.01040% B.C; 0.08400%C; 0.21700% Cu; 0.40900% Mn; 0.01900%S; 0.01620% Sec; % The composition is 0.00198% Co; 0.10200% Si and 98.977% Fe. Corrosion measurements were performed using CHI-660B. In an electrochemical analyzer, there are three conventional electrodes (surface area as working electrode). 2 The Fe molecule, with a density of 0.5024 cm2, is used as a reference electrode with Ag / AgCl and as a counter electrode with surface treatment. This was achieved using the technique of a Pt sheet with an area of ​​2 cm2. Experimental results of the bio-inhibitor, which is the subject of the invention, showed that the electrolyte of the working electrodes... After one-hour immersion periods in the solution, three different methods (EIS, LPR and Tafel) were used. (extrapolation) was evaluated. As a result of electrochemical methods, Leiurus Abdullahbayrami: The venom of this scorpion species reacts with an iron electrode in an acidic environment. corrosion after one hour of immersion; lowest concentration using EIS method 78.5% at 0.020% (w / v) and 84.5% at the highest concentration of 0.160% (w / v). It exhibited inhibition of 79.8% at the lowest concentration of 0.020% (w / v) using the LPR method. and exhibited 83.7% inhibition at the highest concentration of 0.160% (w / v), Tafel By extrapolation method, the lowest concentration of 0.020% (w / v) yielded 76.6%, and the highest concentration was... It was found to exhibit 84.5% inhibition at a high concentration of 0.160% (w / v). Each The inhibition efficiencies obtained by the three electrochemical methods were quite similar to each other. It has been concluded that they are compatible. In the corrosion process occurring at the iron / electrolyte solution interface, This new bio-inhibitor, used for the first time in corrosion prevention, requires one hour of immersion. Leiurus subsequently achieved a high level of inhibition, approximately 85%. low molecular weight peptides present in the venom of the Abdullah Bayrami species The formation of a film layer on the iron surface plays an active role. (As mentioned above) Although the venom of the Leiurus abdullahbayrami species was used in the aforementioned process. However, the venom of any type of scorpion can also be used within the scope of this invention. The technical effect of the invention is the use of scorpion venom as a bio-inhibitor. This In this context, the invention includes a corrosion inhibitor composition as the active ingredient. It contains scorpion venom. The bio-inhibitor described in this invention protects iron surfaces against corrosion. To ensure its protection, the surface should be cleaned and polished, and then the scorpion... By immersing the electrode in an electrolyte solution containing a corrosion inhibitor that poisons the iron, the inhibitor's iron content is neutralized. It is applied by interacting with the surface. In other words, scorpion venom interacts with metal surfaces. It is used as a corrosion inhibitor. 3
