Embodiment 1
[0055] A method for reducing the amount of extractant used from the source of an acidic extraction system and reducing the content of organic matter in the aqueous phase, the compound phase interface modifier used in the method contains the following components by volume fraction: 70% isooctanol, Cyclopentanone 20% and ethyl butyrate 10%.
[0056] The acidic extractant P204 added with the complex phase interface modifier and P204 without treatment were mixed with the solution to be treated in which 8.6g / L nickel was dissolved at 25°C at a volume ratio of 1:1 for 30 minutes, and then Stand still for 30 minutes to obtain extract and raffinate.
[0057] After testing, the P204 raffinate with the compound phase interface modifier contained 203mg / L of nickel and 332mg / L of COD, and the untreated P204 raffinate contained 201mg / L of nickel and 2463mg / L of COD .
Embodiment 2
[0059] A method for reducing the amount of extractant used from the source of an acidic extraction system and reducing the content of organic matter in the water phase, the compound phase interface modifier used in the method contains the following components by volume fraction: n-pentanol 80%, Heptanone 10% and Butyl Acetate 10%.
[0060] The acidic extractant P507 added with the composite phase interface modifier and the untreated P507 were mixed with the wastewater phase to be treated in which 8.6g / L cobalt was dissolved at a volume ratio of 1:1 at 35°C for 30 minutes. Stand still for 30 minutes to obtain the extract phase and the raffinate phase.
[0061] After testing, the P507 raffinate containing the compound phase interface modifier contains 320mg / L of cobalt, and the COD is 262mg / L, and the untreated P204 raffinate contains 316mg / L of cobalt, and the COD is 1526mg / L .
Embodiment 3
