摘要
利用环氧氯丙烷—三乙胺对核桃壳粉进行改性,研究改性后的核桃壳粉对水中磷的吸附情况。采用单要素优化实验,以探讨改性剂的用量、改性时间、吸附质溶液的pH和吸附温度对改性核桃壳吸附效率的影响。单要素实验结果表明:改性核桃壳对磷酸根的吸附最佳条件为20g核桃壳粉加入改性剂三乙胺40m L且改性时间为1.0h;改性核桃壳吸附的最佳条件为pH=7,改性核桃壳的吸附温度为25℃,此时改性核桃壳对废水的去除率达到76.73%,改性效果良好。
In this thesis, the adsorption of the walnut shells modified by epoxy chloropropane and triethylamine on the phosphorus in waste water. The effects of the amount of modifier, modification time, adsorbate pH and temperature on the adsorption efficiency of the modified walnut shell were investigated by single factor optimization experiments. The results showed that the optimum conditions of adsorption were 40 mL modifier of triethylamine, 1 h modification time, pH =7, T =25 ℃, the adsorption rate is 76.73% as good modification effect.
