| 摘 要： | 通过自制阴离子聚丙烯酰胺HPAM对硅藻土矿物改性制备一种有机无机复合吸附剂材料,采用SEM及FTIR技术对复合材料进行表征,并对3种模拟染料废水及2种真实印染污水进行脱色性能研究。结果显示,改性时较佳的HPAM用量在0.8%(质量分数)左右,复合后HPMA高聚物在硅藻土表面大孔内壁形成牙状絮体;通过与未改性硅藻土及颗粒活性炭对上述几种染料废水的处理效果对比,HPMA改性硅藻土复合材料对阳离子染料废水和真实印染废水均具有较高的脱色率。

| Abstract: | A new composite adsorbent was prepared via modifying the diatomite by anionic polyacrylamide HPAM. The adsorbent was characterized by SEM and FTIR. Its dye removal performance was studied by three kinds of dye solutions and two actual dyeing wastewater. Results show that the optimum dose of HPAM in the modification of diatomite was 0.8%. The HPAM formed on the cavity wall of the diatomite was tusklike. The colour removal results of HPMA/diatomite composite, compared with the diatomite and commercial activat... |
