Two kinds of cotton fiber/chitosan composite adsorbents (SCCH and RCCH) were employed to adsorb Au(III) ions from aqueous solution. The adsorption kinetics and adsorption isotherms of the two fibers for Au(III) were investigated. The experimental results revealed that the adsorption kinetics of SCCH and RCCH fibers for Au(III) was described by the pseudo second-order reaction model. The adsorption...
Two types of chitosan-coated cotton fibers (SCCH and RCCH) were applied to remove and recover Hg(II) ions in aqueous solution. The adsorption kinetics and isotherms of the two fibers for Hg(II) were investigated at different temperatures. The results revealed that the adsorption kinetic processes of SCCH and RCCH fibers for Hg(II) followed the pseudo second-order model at lower temperatures and the...
