| 摘 要： | 采用静态吸附法研究北京清河底泥对染料化合物的吸附行为,并探讨了pH值,离子强度,温度等因素对吸附的影响,测定了6种染料的吸附等温线.结果表明,pH值、离子强度是影响吸附的主要因素,温度升高使吸附量增加,6种染料在底泥上的吸附都符合Freundlich方程.吸附动力学研究表明,吸附分为快速吸附(小于1h)和慢吸附(12h以上). |

| Abstract: | The adsorption properties of six kinds of dyes compounds on the sediments in Qinghe were studied through batch technique. The influences of pH, ion strength and temperature on adsorption as well as the adsorption isotherms were discussed and determined. It was shown that pH value and ion strength were the main effect factors on the adsorption, and the adsorption percentage increased with the temperature increase. The adsorption of these dye compounds on the sediment exhibited Freundlich adsorption behavior. The dynamic adsorption indicated that the adsorption process was divided into two steps: fast adsorption (less than 1 hours) and slow adsorption (more than 12 hours). |
