摘　　要：利用环氧氯丙烷对花生壳改性制备吸附剂,并用其吸附水溶液中Cu2+。实验结果显示,花生壳的改性条件为:花生壳5.0 g,浓度为1.5 mol/L NaOH溶液100 mL,环氧氯丙烷5 mL,反应温度30℃,反应40 min;用上述条件改性花生壳0.3 g,吸附初始浓度50 mg/LCu2+溶液,控制溶液的pH为5.0,吸附时间3.0h,对Cu2+吸附率可达96.0%,高于未改性花生壳的70.4%,使吸附率提高36.4%。The peanut hull absorbent was modified by epichlorohydrin,and then it was applied to absorb Cu^2＋ in the aqueous solution.The optimum modified conditions were as follows： peanut hull 5.0g,5mL epichlorohydrin,100mL NaOH solution of 1.5mol/L,temperature 30℃,and reaction time 40min.After that,0.3g modified peanut hull was applied to static adsorption experiments,50mL Cu^2＋ solution of 50mg/L was added,pH 5.0,and adsorption time 3.0h.Under the same conditions,the adsorption rate of Cu^2＋ about the modified and unmodified peanut hull were 96.0% and 70.4%,respectively,and the adsorption rate raised 36.4%.
