Abstract A hybrid adsorbent was prepared in bulk by immobilizing copper onto commercially available natural chitosan as the polymeric matrix for selective removal of phosphate from a reservoir that was severely affected by algae bloom. The batch test showed ∼35 mg g−1 as P sorption capacity for phosphate and the laboratory scale column test for synthetic wastewater yielded the following affinity order: phosphate > sulfate > nitrate. The field-scale adsorption test showed that the effluent T-P satisfied the 0.2 mg L−1 standard. Overall results insinuate that the hybrid adsorbent can be considered as a promising candidate for efficient phosphate removal materials.

用于从受藻华影响的水库中有效去除磷酸盐的有机/无机混合吸附剂

摘要 通过将铜固定在市售天然壳聚糖作为聚合物基质上,制备了一种混合吸附剂,用于从受藻华严重影响的水库中选择性去除磷酸盐。批量测试显示约 35 mg g-1 作为磷酸盐的 P 吸附能力,合成废水的实验室规模柱测试产生以下亲和顺序:磷酸盐 > 硫酸盐 > 硝酸盐。现场规模吸附试验表明,出水总磷满足 0.2 mg L-1 标准。总体结果暗示混合吸附剂可以被认为是有效去除磷酸盐材料的有希望的候选者。
