Paper Title:
Efficient Removal of Cu 2+ with Environmentally Friendly Cellulosic Resin
  Abstract

Because of the environmental danger of heavy metal ions, how to safely and efficiently remove them has became a research hot point. Compared with common methods, adsorption is a better treatment for heavy metal ions. In this paper, Cu 2+ was removed from aqueous solution by a kind of environmentally friendly cellulosic adsorption resin and adsorption performance was investigated. The effects of factors, such as adsorbent dosage and solution pH, on adsorption were investigated. Experimental results displayed that adsorption performed well in neutral solution, and removal was about 94% when used dosage of resin was 0.6 g/L and initial concentration of Cu 2+ was 25 mg/L. Cellulosic resin owned powerful adsorption capability for other heavy metal ions, also. Adsorption behavior abided by Langmuir adsorption isothermal model, and maximum adsorption capability and equilibrium constant was 71.43 mg/g and 1.22 L/g, respectively. Resin could be regenerated by 8% ammonia and regeneration ratio was 74% after 2.5 h.
