| Abstract: | The effects of various factors such as the pH,the reaction temperature,the concentration of Cu(Ⅱ),were investigated with orthogonal experiment.The results showed that the primary influencing factor was pH,the second was the concentration of Cu(Ⅱ),and then reaction temperature.On the optimized conditions of pH 7,the concentration of Cu(Ⅱ) 5 mg·L-1 and temperature 15 ℃,the adsorption rates of Cu(Ⅱ) was up to 98.85 %.And the adsorption characteristic of copper ions on chitosan coincide with the Langmuir model and the Freundlich equation. |
