Abstract
This manuscript reports the solution and micellar behaviour of an antibiotic drug Clindamycine Phosphate (CLN) in aqueous media. Surface tension and specific conductivity were used to find the critical micelle concentration (CMC) and in this way its surface and thermodynamic parameters were calculated. The electrical conductivity was measured as a function of concentration at various temperatures and CMC was calculated in the temperature range of 20-50°C. Thermodynamic parameters i.e. standard free energy of micellization, standard enthalpy of micellization, and standard entropy of micellization, were calculated from CMC value using closed association model.
