摘要
测算了二(2-乙基己基)磷酸钠(NaDEHP)或二(正辛基)磷酸钠(NaDOP)、正辛醇、正辛烷、水和金属盐(CoSO4、NiSO4、FeCl2、CuCl2和CaCl2等)组成的均匀单相微乳液中金属盐水溶液的极限增溶量(Vlim)和金属盐的最大含量(Smax)。相同条件下,NaDOP体系中的Vlim和Smax都比NaDEHP体系中的高得多,这是因为NaDOP中的正辛基的空间位阻小。
The limit of solubilization capacity of aqueous metal salt solution(Vlim))and maximum content of metal salt(Smax))for an homogeneous one-phase microemulsion consisting of sodium di(2-ehtylhexyl)phosphate(NaDEHP)or sodium di(n-octyl)phosphate(NaDOP),n-octanol,n-octane,water and metal salt(CoSO4,NiSO4,FeCl3,CuCl2,CaCl2,et al.),were established.The Vlim) and Smax) in the NaDOP system were higher more than these in the NaDEHP system under the same conditions.This fact was attributed to small steric hindrance of n-octyl in NaDOP.
