【摘要】 采用共沉淀法成功合成了分布均匀的针棒状C-La（OH）₃复合材料，以实现水体中磷酸盐的有效去除。通过一系列实验考察了吸附时间、吸附温度、溶液pH和溶液初始浓度对吸附的影响，并通过循环再生实验考查了吸附材料的重复利用性能。结果表明C-La（OH）₃对磷酸盐的吸附过程是吸热过程，在25℃条件下吸附量为48.681 mg/g,吸附材料可以循环使用五次，是一种既高效又经济的除磷材料。更多还原

【Abstract】 The needle-rod C-La（OH）₃ composite was successfully synthesized by co-precipitation method to effectively remove phosphate from water. The effects of adsorption time, adsorption temperature, solution pH and initial concentration on adsorption were investigated by a series of experiments, and the recycling properties of the adsorbed materials were investigated by recycling experiments. The results showed that the adsorption process of C-La（OH）₃ for phosphate is endothermic, and the adsorption capacity was 48.681 mg/g at 25 ℃. The adsorbent can be recycled for five times, which was an efficient and economical material for phosphorus removal.更多还原
