一种新型光催化剂用于降解腈纶废水研究

Research of a new-type photo-catalyst application in degradation of acrylic fiber wastewater

将1,10菲啰啉和铁Fe^2＋溶液配成络合物负载到D113树脂上作为可见光催化剂,利用该催化剂对腈纶废水进行了降解研究,考察了该负载型铁氮配合物催化剂处理腈纶废水的影响因素。由实验结果可知,该催化剂处理腈纶废水最佳条件为：过氧化氢浓度为400 mg/L,催化剂用量为5 g/L,最佳pH值范围为4-9,COD降解率可达68.7%,实现了在温和的反应条件下,即常温、常压、宽pH范围进行反应,充分利用了可见光来处理难降解有机物。

1,10 phenanthroline and Fe2＋ formate organic ion complex was loaded on a cationic exchange resin D113 as a photo-catalyst for the degradation of acrylic fiber wastewater.The influencing factors in treating acrylic fiber wastewater using this complex were investigated.The optimal reaction conditions for this research are as follows： the concentration of H2O2is 400 mg/L,the amount of catalyst is 5 g/L and optimal range of pH is 4~9.The COD degradation of acrylic fiber wastewater is up to 68.7%.It realized the effect of the degradation of acrylic fiber wastewater under visible irradiation and facile reaction conditions：normal temperature, natural pressure and wide pH range.
