- Abstract:
- In this study, chitosan resin was prepared with an improved drop-ball-forming method using chi.tosan as the raw material. Epichlorohydrin was used to cross-link the resin in order to enhance rigidity of res.in, and a new chitosan cross-inked resin was synthesised, The pH of solution, temperalure, time and initialconcentralion of Pb( ll ) were discussed to assess the adsorption performance. Besides, adsorption thermody-namic and kinetic of Pb ( Il ) was studied, The results showed that the pH was the main influencing factor,after 4.5 hours of adsorption at pH =6.0 and 30 ℃, the maximum adsorption capacity ( 105.0 mg/g) wasreached. Moreover, Temkin equation and Pseudo gecond-order equation were used to describe the thermody.namic and kinelics. The correlation coefficients were 0, 9995 and 0, 9926 respectively. The results showed thatthe removal mecbanism may include physical adsorption and chemical adsorption.
