Oxidative Degradation of Neonol AF 9-12

摘要

The oxidative degradation of a difficultly degradable surfactant,oxyethylated isononylphenol(Neonol AF 9-12),with aqueous hydrogen peroxide containing iron(III)chloride was studied tensimetrically.The wide application of surfactants,primarily,household chemicals,leads to wastewater pollution with these agents.As a rule,surfactant-containing municipal wastes of large cities are treated at waste-water treatment plants in combination with some industrial wastes.However,biodegradation of some surfactants is not sufficiently fast to decrease their content in decontaminated wastewater to the level of the maximum permissible concentration(MPC).
