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 ...
