摘　　要：采用共混交联法合成了纳米TiO2/壳聚糖复合物,研究了该吸附剂在废水中吸附苯酚的效果。考察了吸附剂用量、吸附时间、吸附温度、pH等因素对废水中苯酚吸附率的影响。结果表明:当吸附剂用量为0.20 g,吸附时间为30 min,pH为5,吸附温度为40℃时,交联改性剂在废水中吸附苯酚的吸附率为58.7%。用Langmuir和Freundlich等温吸附模型进行拟合,结果表明该吸附符合这两种吸附模型。Nan-TiO2/CTS complex was synthesized by co-crosslinking method and was used as adsorbent to capture phenol from wastewater.The effects of four factors on absorption of phenol from waste water with nano-TiO2/CTS complex.Results show that when the dosage of the adsorbent was 0.2 g,adsorption time of 30 min,pH of 5,adsorption temperature of 40℃,the adsorption rate of phenol from wastewater was 58.7%.Langmuir and Freundlich isothermal adsorption models were used to fit the adsorption.The adsorption conformed to the two adsorption models.
