摘要
与DBS/TritonX—100混合胶束体系比较,DBS/TritonX—100/n—C_5H_(11)OH/H_2O体系复配O/W微乳液对Fe(Ⅲ)BPHA光度分析具有更好的增敏作用.分配系数测定表明此结果与O/W微乳液对BPHA有更好的增溶作用有关.本文还通过紫外光谱测定研究了O/W复配微乳液体系DBS/TritonX—100/n—C_5H_(11)0H/H_20对显色剂BPHA的增溶机理.
The sensitized reaction of built-up O/W microemulsion DBS/ Triton X-100/ C5H11OH/ H2O on Fe(Ⅲ)-BPHA complexes was higher than that of mixed micell DBS/ Triton X-100/ H2O. This result showed by measurement of distribution constant KD was related to the greater solubilization capacity of BPHA in the built-up O/W microemulsion system than that in the mixed micell. The solubilization mechanism of BPHA in the built-up O/W microemulsion was also studied by the measurement of Ultraviolet spectrum.
