以花生壳、柑橘皮的不同炭化材料和碳纤维作为水中污染物的吸附剂，对重金属Cu2+进行了吸附研究。吸附试验结果表明：当改变水中pH时对吸附效果影响比较大，pH 5.5时吸附剂对水中Cu2+的吸附量最大；吸附时间在90 min后达到了吸附平衡状态；花生壳、柑橘皮吸附效果最好的加工炭化温度为250℃。
Research on adsorption of Cu 2+in water with different carbonized materials like peanut shell and citrus peels and carbon fibers as adsorption agents is carried out .The results show that the effect is evident when pH in water changes;the agents reach peak adsorption of Cu 2+with pH 5.5 and the adsorption reach equilibrium after 90 min;the optimal carbonization processing temperature in terms of best adsorption effect of peanut shell and citrus peel is 250 ℃.
