| Abstract: | Polyaluminium chloride sludge(PACS) refers to the by-product from water treatment plant where polyaluminium chloride(PAC) was used as coagulant.Groups of experiments were designed to investigate the kinetics and thermodynamics of phosphorus adsorption onto PACS.The results revealed that the phosphorous adsorption capacity could account for 75% to 90% of equilibrium adsorption capacity after the reaction occurred 1 h.After that,the adsorption rate became slower and the adsorption reaction reached equilibrium... |
