摘要
采用批式吸附法研究河体底泥对活性艳蓝X-BR的吸附特性.吸附动力学试验结果表明吸附可划分为高速吸附(小于6h)和缓慢吸附(6h以上)两个阶段.活性艳蓝X-BR吸附等温线符合Freundlich方程,pH值、离子强度、温度是影响吸附的重要因素,在pH5左右,色度去除率最高;提高离子强度和温度有利于吸附.
The adsorption properties of brilliant gaudy blue X-BR on the sediments in Lijiang river were studied through batch technique.The dynamic adsorption indicated that the adsorption process may be divided into two stages,that is,fast adsorption (less than 6 hours) and slow adsorption (more than 6 hours).The adsorption data are fitted to Freundlich equation.It shows that pH value and ion strength were the main effect factors on the adsorption,and the maximum adsorption of the dye was observed at about pH5.With increasing ion strength and temperature,adsorption for brilliant gaudy blue X-BR was slightly increased.
