| 摘 要： | 以石英砂为载体,用碱性沉积法制备了铝盐改性砂,在静态试验条件下,考察了铝盐改性砂对锌的吸附性能及其影响因素.结果表明,在pH值为中性的条件下,铝盐改性砂的吸附效果优于石英原砂,石英原砂对Zn2+去除率为41%,铝盐改性砂对Zn2+去除率可达到68%;随着Zn2初始浓度的增大,铝盐改性砂对Zn2+的去除率逐渐减少;铝盐改性砂对Zn2的去除率随着pH值的升高而提高,当pH为9时,去除率接近100%. |
| 关 键 词： | 铝盐改性砂 制备 除锌 吸附性能 |

| Abstract: | In this experiment quartz sand was chosen as a carrier to be coated by aluminous salt with the deposition process at alkaline condition,and then the adsorption capability and influencing factors for zinc removal by aluminous salt modified sand were investigated respectively.The experimental results showed that the adsorption capability of aluminous salt modified sand was significantly improved,and the removal efficiency of Zn2+ by aluminous salt modified sand was much better than that by raw quartz sand und... |
| Keywords: | aluminous salt modified sands preparation zinc removal adsorption capability |
