Abstract

Abstract: The in situ binding of CoS nanoparticles to gelatin was studied using UV-visible and FT-IR methods at pH 11.00 and different temperatures.The absorbance data were analyzed according to Lineweave-Burk double-reciprocal equation.K,the binding constants of the compound at different temperatures(293 K: 3.01×10³L/mol;301 K: 2.12×10³ L/mol;313 K: 1.85×10³ L/mol) and the thermodynamic parameters(ΔrH_m =-17.93 kJ/mol;ΔrS_m =4.93 J/K·mol;ΔrG_m =-19.37/-19.41/-19.47 kJ/mol) at correspondence temperatures were obtained.The negative enthalpy(ΔrH_m) and positive entropy(ΔrS_m) values indicate that electrostatic force played the major roles in the binding reaction of nano-CoS with gelatin.The results provide useful information for exploring the chemical mechanism of interaction between nanoparticle and fibrous protein.

Key words: nano-CoS, gelatin, in situ binding reaction
