Thermally treated egg shell materials were prepared at different temperatures. The samples were investigated by means of FT-IR and thermogravimetric analysis (TGA). The adsorption behaviour of malathion on egg shell and its thermally treated samples was studied using batch method and gave uptake capacities up to 0.964 mmol/g. Adsorption kinetics as well as the adsorption isotherms were discussed. Regeneration of the loaded adsorbent beads towards the successive cycles was also clarified. The adsorption of malathion is maintained until the third cycle without a significant activity loss.
采用不同温度制备了热处理鸡蛋壳材料。通过傅里叶变换红外光谱（FT-IR）和热重分析（TGA）对样品进行了研究。采用批量法研究了马拉硫磷在鸡蛋壳及其热处理样品上的吸附行为，吸附容量高达 0.964mmol/g。讨论了吸附动力学和吸附等温线。还阐明了负载吸附剂珠粒在连续循环中的再生情况。马拉硫磷的吸附在第三周期仍保持，没有明显的活性损失。
