ABSTRACT
Water solubility enhancements of acenaphthene by single2surfactant , such as SDS , CTMAB ,
Triton X2100 , and mixed2surfactant , such as Triton X21002SDS , Triton X21002CTMAB , were
compared and evaluated.

The partition coefficients ( K mn ) of acenaphthene be2
tween water and monomer , such as SDS , CTMAB , Triton X2100 , are 1130 10 3 , 0192 10 3 ,
and 1130 10 3 , respectively , at surfactants concentrations below CMC ; the partition coefficients
( K mc ) of acenaphthene between water and micellae are 5164 10 3 , 1150 10 4 , and 5157 10 3 ,
respectively , at surfactants concentrations above CMC. Acenaphthene was solubilized synergistcally
by Triton X21002SDS and Triton X21002CTMAB mixed surfactants , which results from increasing
partition coefficients of acenaphthene between water and mixed surfactant.
