  • 摘要: 采用硼酸-硼砂两阶段固定化方法制备PVA-SA复合微囊藻球,综合考察了硼酸(H3BO4)、氯化钙(CaCl2)、硼砂(Na2B4O3·10H2O)、聚乙烯醇(PVA)和海藻酸钠(SA)等因素对藻球性能、固定化过程中PVA泄露及Ni2+去除效果等的影响。结果表明,在以上各因素水平分别为3.5%、2.0%、3.0%、9%和1%时,成球效果、藻球性能较好,固化过程中PVA泄露量较小,Ni2+去除效率较高。两阶段固定化方法可以成功解决PVA-SA包埋固定化技术存在的水溶胀性问题,为其实际运用提供了可能性。
    Abstract: A PVA-SA composite ball of Microcystis aeruginosa was prepared by the boric acid-borax two-stage immobilization process. A comprehensive study on the factors boric acid (H3BO4), calcium chloride (CaCl2), borax (Na2B4O3·10H2O), polyvinyl alcohol (PVA), and alginate sodium (SA) was performed, with review indicators such as performance of the composite ball, leaking of PVA in the immobilization process, and removal rate of Ni2+ ions, etc. The experimental results showed that reasonable dosages of the above factors were 3.5%, 2.0%, 3.0%, 9%, and 1%. These factor levels guarantee better performance of the composite ball, lower PVA leaking, and increased removal efficiency of Ni2+ ions. The two-stage immobilization process can solve the swelling problem of PVA-SA immobilization technology successfully and offers a possibility for its practical application.
