Rao, K Jagajjanani (2009) Solubilization and Biodegradation of Naphthalene in Presence of Sapindus Mukorossi − Synthetic Mixed Surfactant Systems. MTech by Research thesis.
Solubilization efficiencies of naphthalene by micellar solution of a plant–based surfactant extracted from fruit of Sapindus mukorossi (Reetha), and the synthetic surfactants like nonionic (TritonX–100 or TX–100), cationic (Cetyl trimethyl ammonium bromide or CTAB), anionic (Sodium dodecylbenzenesulfonate or SDBS; Dioctyl sodium sulfosuccinate or AOT; Sodium octanesulfonate or SOS) in their single and as well binary mixed (plant – synthetic) systems were measured and compared. The solubilization efficiency of single surfactants followed the order TX-100 > CTAB > Reetha = SDBS > AOT > SOS. The mixed surfactant systems show negative deviation in molar solubilization ratio (MSR) from the ideality. The ascending order of % change in MSR (∆MSR) are TX–100 – Reetha < CTAB – Reetha < SDBS – Reetha < AOT – Reetha < SOS – Reetha. The mixed micellar solution for a particular combination also exhibits
∆MSR is more negative when interaction parameter for the mixed micelle (β) is more negative.
