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 m
icell DBS/Triton X-100/H2O. This result showed by measurement of distr
ibution constant KD was related to the greater solubilization capacity
of BPHA in the built-up O/W microemulsion system than that in the mix
ed micell. The solubilization mechanism of BPHA in the built-up O/W mi
croemulsion was also studied by the measurement of Ultraviolet spectru
m.
