| 摘 要： | 合成了新型螯合树脂聚苯乙烯负载葡糖胺(PS-GA),并研究了所合成树脂对Pd(II)的吸附容量、吸附动力学、等温吸附等静态吸附性能及影响吸附的因素。结果表明:该树脂对Pd(II)的吸附量较高;树脂对Pd(II)的吸附为液膜扩散控制,吸附的活化能为59.76 kJ/mol;在实验浓度范围内,对Pd(II)的等温吸附符合弗伦德利希方程;较高温度有利于吸附;树脂可用2%的硫脲-0.1 mol/L HNO3清洗再生,再生后仍保持良好的吸附能力。 |

| Abstract: | A novel chelating resin,polystyrene-supported glucosamine(PS-GA),was prepared and its static adsorption properties for Pd(II) such as capacity,dynamics and isotherm adsorption were studied,as well as various factors affecting the adsorption.The results indicated that: This resin had higher adsorption capacity for Pd(II).The adsorption dynamics indicated that adsorption was controlled by the liquid film diffusion.Value of adsorption activation energy calculated was 59.76 kJ/mol.The adsorption isotherms approximately fitted Freundlich equation within the range of experimental concentration.The suitable adsorption conditions were higher temperature.In addition,they had also high adsorption capacity after being regenerated by 2% thiourea in 0.1 mol/L HNO3. |
| Keywords: | polystyrene-supported glucosamine(PS-GA) adsorption property Pd(II) |
