Embodiment 1
[0035] A kind of microemulsion membrane medicament that can be used for treating waste water or cleaning polluted soil sample of the present invention, comprises membrane phase and internal water phase, and membrane phase is formulated by the component of following volume fraction:
[0036] Industrial kerosene (or diesel) 42% to 60%,
[0037] Support film agent 3%,
[0038] Carrier substance 6% and
[0039] water balance;
[0040] The volume ratio of the membrane phase and the internal water phase (that is, the commonly referred to as the oil-to-internal ratio) is 1:1 (1: (0.5-2) is acceptable).
[0041] The supporting membrane agent selected in this example is N-butoxypolyoxyethylene polyoxypropylene glycol, N-(1.2-dicarboxyethyl)-N octadecylsulfosuccinamic acid tetrasodium salt, hydroxyethylethylene One of disodium diamine diacetate, octylphenoloxy polyoxyethylene ether alcohol, polyethyleneimine, and polyisopropyleneimine or a combination of any two of them.
