Sorption Purification of Sewage from Aromatic Nitro Compounds
The possibility of using activated carbons in wastewater treatment from aromatic nitrophenols and nitrosulfonic acids was investigated. The main parameters of the adsorption process that provide the maximum degree of purification are determined: the amount of activated carbon and the pH of mother solutions. The method of regeneration of the extracted activated carbon by treatment with sodium hydroxide solution was studied, the optimal conditions of extraction were determined.
