Adsorption of Silver Nitrate by Cotton Fabrics Containing Polyethylene Sulfide

Abstract

The adsorption of silver nitrate from aqueous solution by polyethylene sulfide-containing cotton fabrics was investigated. The adsorption could be described by a Freundlich-type isotherm with n = 1. AHo was calculated from adsorption isotherms and from the equilibrium constant of complex formation and similar results of -5.6 and -5.4 kcal/mole were obtained, respectively. At low silver nitrate concentrations most of the silver nitrate present in solution could be adsorbed. It was found that adsorption by polyethylene sulfide in the fabric was much higher than that of homopolyethylene sulfide.
