Abstract
A new purification method for di-alkyl phosphoric (phosphonic, phosphi nic) acid extractants has been developed based on the principle that m ost of the surfactant molecules exist in the middle phase microemulsio n. Comparing with the method of copper salt precipitation and crystall ization, this method is much easier and cheaper.
