MICELLIZATION STUDIES OF DODECYL BENZENESULFONIC ACID AND ITS INTERACTION WITH POLYVINYLPYRROLIDONE
摘要:
Dodecyl benzenesulfonic acid (DBSA) surfactant was used in the present study to find the effect of concentration on its electrical conductance in solution from 293323 K above and below the critical micelle concentration (CMC). The micellization parameters i.e. degree of counter ion binding (b), aggregation number (n) and number of counter ion micelle (m) were measured. The interaction of DBSA with polyvinylpyrrolidone (PVP) was also studied at 293 K through conductance and surface tension measure ments. A number of important parameters i.e. critical aggregation concentration (CAC), Gibb’s free energy (DG) and binding ratio (R) were determined and the effect of NaCl on the CAC and polymer saturation point (PSP) was also investigated.
