Volumetric and viscometric studies of cefepime hydrochloride in water and normal saline from (278.15 to 313.15) K

Abstract

Density (ρ) and viscosity (η) measurements were carried out for cefepime hydrochloride in water and 0.9 mass % normal saline from (278.15 to 313.15) K. The dependence of density and viscosity on temperature and concentration has been correlated. Apparent molar volumes, standard partial molar volumes, and the viscosity B-coefficient of cefepime hydrochloride were calculated from the experimental measurements. The results are used to establish the nature of solute–solute. Solute–solvent interactions and structure breaking effect of cefepime hydrochloride have been discussed using the Helper equation and the Jones–Dole equation. The relationship between relative changes in viscosity and solute-mixed solvent interaction has been probed.
