摘要
以Na OH为预处理剂,环氧氯丙烷为醚化交联剂,对糠醛渣进行改性,并探究其对水中Cr(VI)的吸附性能。结果表明,当Cr(VI)溶液初始浓度为100mg·L-1,改性糠醛渣加入量为20mg,溶液p H值为2,吸附温度为328K,吸附时间为120min时,饱和吸附量可达93.98mg·g-1。
Furfural residue was modified with the sodium hydroxide as pretreatment agent and the epichloro-hydrin as etherification cross-linking agent,and the adsorption behavior of Cr（VI）adsorption onto the modified furfural residue was discussed.The results showed that the adsorption quantity of Cr（VI） reached 93.98mg·g^-1 when the initial Cr（VI）concentration was 100mg·L^-1,themodified furfural residue amountwas20 mg,the solution p H value was 2,the adsorption temperature was 328 K and the adsorption time was 120 min.
