  • 摘要: 以氯化铁为铁源，硼氢化钠为还原剂，壳聚糖为稳定剂，采用液相还原法制备壳聚糖稳定纳米铁（CS-nZⅥ）；研究了印染废水中常见助剂NaNO3、Na2SO4、NaH2PO4、K2Cr2O7、EDTA二钠盐存在下，超声波辅助CS-nZⅥ对酸性品红（AF）降解的影响。结果表明，反应15 min，0.01 g CS-nZⅥ对25 mL、100 mg/L AF的去除率高达99.9%；各种助剂的存在使得纳米铁表面不同程度失活，阻碍反应的进行，使得AF的去除率下降。NaNO3、K2Cr2O7、EDTA二钠盐与纳米铁发生反应，与AF存在明显的竞争作用。重复利用实验表明，CS-nZⅥ重复利用7次仍具有一定的反应活性。此外，CS-nZⅥ对加标（50 mg/L）实际废水中AF的去除率达到99%以上，表明CS-nZⅥ是一种潜在的环境修复材料。
    Abstract: Chitosan-stabilized zero-valent iron (CS-nZⅥ) was prepared by chemical reduction in aqueous solution starting from ferric chloride as the raw material,sodium borohydride as reducing agent and chitosan as stabilizing agent. A series of experiments were performed to analyze the influence of several typical additives in dyeing wastewater,including NaNO3, Na2SO4, NaH2PO4, K2Cr2O7 and EDTA-Na2. The results showed that 99.9% of acid fuchsine (AF) was removed from aqueous solution with assisting ultrasound under the conditions,including an initial AF concentration of 100 mg/L,25 mL solution,using 0.01 g CS-nZⅥ after reacting for 15 min. The presence of additives made the surface of nZⅥ inactive and hindered the reaction,therefore, decreased the removal of AF. NaNO3,K2Cr2O7 and EDTA-Na2 could be reduced by CS-nZⅥ,and they competed with AF obviously. Meanwhile, experiments showed that recycling reuse of CS-nZⅥ seven times still had certain reactivity. In addition,the removal efficiency of AF in actual dyeing wastewater with addition of 50 mg/L was above 99% using CS-nZⅥ and it indicated that CS-nZⅥ will be a kind of potential material of environmental remediation for dyeing wastewater.
