Study on kinetics and thermodynamics of phosphorus adsorption onto PAC sludge
聚合氯化铝污泥对磷的吸附动力学及热力学

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...
