Simple model for the calculation of concentration and temperature dependent refractive index of different solutions

Simple analytical models for the calculation of concentration (c) and temperature (T) dependent refractive index i.e., n(c,T) values six solutions namely, three electrolyte (KCl, NaCl, CaCl2), a polar (glucose), non-polar (ethyl acetate), protein (bovine serum albumin) have been proposed. The obtained using our proposed compared with corresponding other reported experimental values. A fairly good agreement between them has obtained.
