Tourmaline molybdenum-loaded inorganic inhibiting sulfate reducing bacteria powder and its preparation method

Abstract

The invention provides an inorganic tourmaline powder containing molybdenum for suppression of sulfate reducing bacteria and a preparation method, which relates to an antibacterial agent and a preparation method. The invention solves the problem that that the prior organic antibacterial agent has poor security, poor heat-resistant property, easy decomposition and short service life. According to quality percentage, the invention is made of the tourmaline of 60-99.99 percent and the ammonium molybdate solid of 0.01-40 percent. The preparation method is as follows: 1. The nano or submicron tourmaline is put into deionized water for stirring; 2. Nitrate solution is added and PH value is adjusted to 4-8; 3. The molybdenum and a dispersant are added for stirring; 4. With decompression, extraction and filtration as well as separation, the solution is washed by deionized water; 5. The powder is dried after separation and washing; 6. With grinding and calcinations of the dried powder, the powder is grinded again, and then the inorganic antibacterial powder is prepared well. With surface modification, ion exchange and solid-phase synthesis, the invention adopts the nano or submicron tourmaline, not only effectively increasing the amount of the loaded molybdenum, but also improving the antimicrobial effect of the antimicrobial agent.

Description

technical field [0001] The invention relates to an antibacterial powder and a preparation method thereof, in particular to a molybdenum-supported natural tourmaline inorganic antibacterial powder and a preparation method thereof. Background technique [0002] In recent years, with the accelerated development of the national economy, the pollution of industrial wastewater, especially sulfate wastewater, has been quite serious. The groundwater of many large cities in my country has been polluted by sulfates to varying degrees. Discharge of sulfate-containing acidic wastewater directly into the water body without treatment will acidify the receiving water body, reduce the pH value of the water body, endanger aquatic organisms, and cause potential corrosion; this type of acidic wastewater will also damage the soil structure and reduce crop yields. Sulfate wastewater has a long incubation period, and although it has the activity of natural reducing bacteria, it has become a very...
