摘要: A coordination polymeric xerogel based on copper acetate and 2-amino-5-mercpto-1,3,4-thiadiazole was prepared characterized by SEM, EDX FTIR, respectively. It exhibits favorable adsorption behavior for sulfonic dyes such as Thymol blue, Acid fuchsin Methyl orange. The effects of various experimental parameters including initial dye concentrations, exposure time, temperature, pH ion strength were investigated. Adsorption kinetics, isotherms mechanism also analyzed. desorption profile revealed that a significant portion (>80%) could be desorbed using sodium chloride aqueous solution eluting agent.
