Abstract

The study was conducted regarding the adsorption effect of Cr(VI) on polyethylenamine cellulose, the affecting factors on the adsorption of Cr(VI), such as pH value, adsorption time, polyethylenamine cellulose dose and initial concentration of Cr(VI) were investigated. The results showed that adsorption efficiencies of Cr(VI) is more than 90%, the suitable conditions for the adsorption are as following: pH 2, adsorption time 10h, polyethylenamine cellulose 10 g/L, initial concentration of Cr(VI) 10 mg/L. The adsorption isotherms could be well fitted by both Langmuir and Freundlich equation. The law of dynamics for the adsorption can be simulated by pseudo-first order and pseudo-second order kinetics models.
