以壳聚糖(CTS)与纳米CaCO3为原料,采用简单的凝胶改性法,制备出吸附性能更佳的CTS/纳米CaCO3复合材料。利用XRD,SEM,FT-IR以及AAS等对其进行结构和性能分析。以硝酸铜溶液为模拟废液进行吸附实验,探讨CTS/纳米CaCO3复合吸附材料的吸附性能。通过简单的改性实验,成功制备了CTS/纳米CaCO3复合吸附材料。在28℃下,探究了吸附时间,模拟溶液pH,以及Cu2+的不同初始浓度对吸附性能的影响。

Using CTS and nano calcium carbonate (CaCO3) as raw materials,CTS/Nano CaCO3 composite materials with better adsorption properties were prepared through gel method.The structural characteristics were analyzed by XRD,SEM,FTIR and AAS.The adsorption properties of the CTS/nano CaCO3 were evaluated by using Cu(Ⅱ) nitrate solution as a simulated adsorption experiment.The results showed that the CTS/nano CaCO3 were successfully prepared.The effects of adsorption time,pH value of simulated solution,and different initial concentrations of Cu(Ⅱ) on adsorption performance were investigated at 28℃.The results shown that the adsorption performance of CTS/nano CaCO3,obtained by composite modification,was better than that of CTS or nano CaCO3.
