离子液体对含酚废水的处理效果研究

Effect of Ionic Iiquids for Treatment of Wastewater Containing Pheno

本文采用亲水型离子液体[C_(10)mim]Br对滤膜进行改性后对含酚废水进行处理,采用4-氨基安替比林分光光度法测定挥发酚,并研究采用离子液体改性后的滤膜对含酚废水中酚类物质的去除效率.考察了离子液体用量、滤膜浸泡时间、pH、含酚废水初始浓度、盐浓度等的影响.通过正交试验得到最佳实验条件:离子液体最佳用量为1.5 g;最佳浸泡时间为10 min;最佳pH值为9.0.

this paper explores the use of hydrophilic ionic liquids [c10 mim]Br membrane for treatment of phenolcontaining waste water by modified effect of 4-amino antipyrine Spectrophotometric Determination of volatile phenols and study on using Ionic Liquid modified membrane to phenols in phenol-containing waste water removal efficiency. Amount of ionic liquids,membranes were investigated soaking time,initial concentration,pH, phenol-containing waste water salt concentration effect. Best experimental conditions by orthogonal test:[c10 mim] Br effective;the best dosage of 1.5 g;best time to soak for 10 min;optimum;pH value of 9.0.
