AI Technical Summary

Problems solved by technology

Among them, the chemical method is currently unable to be put into industrial operation due to its high processing cost and complicated equipment and technology. The biological method is greatly affected by environmental factors such as sewage influent concentration, reaction temperature, and reaction pH, and p-nitroaniline has strong toxicity and poor degradability. are very limited in practical applications
Among the physical methods, the removal rate of the physical adsorption method is low, only about 80%. The organic solvent in the complex extraction method may cause secondary pollution to the environment, while the membrane separation method has relatively high infrastructure and operating costs, requiring Regular chemical cleaning, and its concentrated wastewater treatment is difficult

The water treatment chemical is made from 3, 7-dimethyl-6-octenal, 4-formylphenylBeta-D-allopyranoside, aluminum sulfate, trans, trans-2, 4-nonadienal, 2-hydroxyl-4-isopropyl-2, 4, 6-cycloheptatriene-1-one, apha-aminoisocaproic acid, potassium alginate, picrasinol B, (S)-2-(fmoc-amino)caproic acid, acutumidine, 1-pentadecanol, 3, 7, 11-trimethyl-1, 6, 10-dodecatriene-3-ol, amentoflavone, and 2-ethyl-2, 5-dimethylhexanoic acid. The water treatment chemical has the advantages that the chemical has high ability to complex with the para-nitroaniline, complex precipitant forms fast, the removal rate of the para-nitroaniline is up to 99%, and the chemical is low in toxicity, low in use amount, free of harm to water and low in treatment cost.

Description

technical field [0001] The invention relates to a water treatment agent for removing p-nitroaniline in water, belonging to the technical field of environmental protection. Background technique [0002] p-Nitroaniline is a yellow needle-like crystal with a strong pungent odor, with a boiling point of 332°C and a density of 1.424g / ml. p-Nitroaniline is slightly soluble in cold water, soluble in boiling water, and miscible with ethanol, ether, benzene and acid solutions. [0003] p-Nitroaniline is an extremely important intermediate in the dye industry, and is also a raw material for anti-aging agents, light stabilizers, and developers. p-Nitroaniline is a harmful substance that seriously pollutes the environment and endangers human health, and is a "carcinogenic, teratogenic, and mutagenic" three-causing substance. Due to its long-term residue, bioaccumulation, carcinogenicity and other characteristics, it is listed as 129 pollutants for priority control by the US EPA; in my...
