利用滩涂污灌土壤制备吸附剂OA北大核心CSCDCSTPCD
Preparation of adsorbent by irrigating soil of beaches
研究了滩涂污灌土壤吸附剂的制备方法。通过正交实验,比较了氯化锌、磷酸、氢氧化钾、盐酸几种活化剂在不同秸秆加入量、活化剂浓度、活化时间、活化温度的情况下制备的吸附剂,对水中邻硝基甲苯的吸附效果影响。实验结果表明,选择盐酸活化法制备吸附剂,在秸秆加入量为15%,经2 mol/L的盐酸按液固比为1∶1浸泡处理滩涂污灌土壤后,用氮气做保护气在400℃的条件下碳化1 h,制备的土壤吸附剂对水中邻硝基甲苯的吸附效率可以达到90%以上。
This article studied the preparation methods of the adsorbent by irrigating soil of beaches.From a series of orthogonal tests,the absorbing ability of the synthesized adsorbent to o-nitrotouene in water was investigated by adding several activators（ZnCl2,HCl,KOH and H3PO4） under various conditions such as the dosage of added straw,concentration of the activator,the time of acting and the temperature of the activator.The result showed that HCl was the best ac…查看全部>>
