| Abstract: | In order to improve activated alumina's performance of phosphorus removal in waste water,the activated alumina as a carrier was modified with aluminum sulfate solution by impregnation method.Pore volume,average pore size and BET surface area were determined.The effects of adsorption time,pH,initial concentration of wastewater,modified dosage and other factors on the phosphorus removal from wastewater were studied.Modified activated alumina's adsorption mechanism of phosphorus was discussed.The results showe... |
