Abstract

Abstract: A modified adsorbent, namely hydroxypropyl cellulose xanthate (HCX), was synthesized for removal of heavy metal ions from aqueous solution. HCX was prepared by introducing xanthogenated groups, and the sulfur group in HCX was confirmed by scanning electron microscope, Fourier Transform Infrared, nuclear magnetic resonance, and ultraviolet-visible spectra. The sulfur group plays a significant role in chelating with heavy metal ions. Adsorption of copper and nickel ions by HCX was conducted, and the factors of adsorption time, temperature, adsorbent dose, and pH value were investigated. The removal rate of copper and nickel ions were up to 98 and 83% under the optimum condition, respectively. Adsorption isotherms indicated that Langmuir isotherm model had a better linearity and the maximum adsorption capacities of copper and nickel ions were 126.58 and 114.29 mg g −1 respectively, confirming that the affinity of metal ions onto sulfur-bearing groups was considerable.
