【正文】 ophication and subsequent deterioration of water quality [1,2]. In fact, the presence of trace amounts of phosphate (even less than 1 mg/L) in the treated wastewater from municipalities and industries is often responsible for entrophication in receiving water bodies [3]. Therefore, removing phosphate is very necessary before discharging wastewater into water techniques such as chemical precipitation [4], adsorption [5], reverse osmosis [6], biological removal [7,8], and constructed wetlands [9] have been employed for removal of phosphate from wastewaters. Among these available approaches,chemical precipitation and biological removal are generally not able to meet the stringent effluent standards and reverse osmosis is a high capital cost, while the adsorption methods proved to be more promising due to their low cost, effective treatment in dilute solutions, and high uptake capacity. Another attractive feature of this technique is that the nutrientloaded ?lters can be used in agriculture as phosphate fertilizer and soil conditioner [10]. A large number of materials from natural minerals to synthetic ones have been used as adsorbents to adsorb phosphate from wastewater [11–15]. Recently, the application of low cost and easily available materials for phosphate removal has been widely investigated,such as fly ash [16–18], blast furnace slag [19–21], iron oxide tailing [22], red mud [23,24], Cabased adsorbents, and ironbased pounds [25–27].Based on the risk of very dilute phosphate in water and more stringent effluent standards imposed, it is necessary to develop new ads
