A complex extraction was used for the treatment of wastewater containing dimethylamine(DMA).The effects of the diluent and complexing agent and their concentrations,solution pH,and the volume ratio of oil to water on the equilibrium distribution coefficient were systematically studied.The results showed that the extraction was a rapid and exothermal reaction,and the enthalpy of the extraction reaction ΔH was-6.50 kJ/mol with di(2-ethylhexyl)phosphoric acid as the complexing agent and hexahydrobenzene as the diluent.The composition of the extracted species was deduced,and the ratio of P204:DMA was 1:1.The maximum removal rate of DMA was 93.0% by one stage extraction under the conditions of pH=11.87,oil to water volume ratio of 0.25,and a volume ratio of 0.1 of the extractant to the diluent in oil phase.The mechanism of complexation reaction was investigated by infrared,and there were hydrogen bonding and ion-association reaction.
