摘要
目的探讨壳聚糖固载的金属卟啉磁性微球的合成方法及对甲基橙废水的催化效果,寻求成本低廉、高效节能的染料废水处理方法。方法采用磁流体包埋法制备壳聚糖固载钴卟啉磁性微球(MCSCoTPP微球)和壳聚糖固载锰卟啉磁性微球(MCSMnTPP微球),并通过扫描电镜、透射电镜、紫外吸收光谱等方法进行表征,考察微球在不同pH值下对甲基橙废水的催化降解及回收重复利用情况。结果成功制备了新型的金属卟啉壳聚糖磁性微球,在以自然日光做光源时,MCSMnTPP微球和MCSCoTPP微球对甲基橙废水具有较好的催化效果,催化效率分别达到81%和93%,且分离回收方便,重复利用多次仍具有较高的催化活性。结论壳聚糖金属卟啉磁性微球是潜在的治理染料废水的优良催化剂。
Objective To study the synthetic methods and methyl orange wastewater catalytic efficiency of Magnetic chitosan-supported metalloporphyrin nanospheres.Methods Magnetic chitosan nanospheres immobilizing cobalt（MCSCoTPP） and manganese tetraphenylporphyrins（MCSMnTPP） were synthesized by embedding magnetic fluid and were characterized by SEM,TEM and solid UV spectrum.Meanwhile,these nanospheres were employed as catalysts for the degradation of methyl orange wastewater under different pH conditions and reused.Results Magnetic chitosan-supported metalloporphyrin nanospheres were synthesized successfully;MCSMnTPP and MCSCoTPP were highly efficient catalysts to methyl orange wastewater under natural sunlight and the catalytic efficiencies reached to 81% and 93%,respectively.Conclusion Magnetic chitosan-supported metalloporphyrin nanospheres are ideal catalysts for methyl orange wastewater.
