Abstract

Background: Malachite green (MG) is widely used as a fungicide, Bactericide parasiticide in the aquaculture industry, as a food additive, medical disinfectant, and also, as a dye for materials such as silk, leather, paper, etc. In this study, the photocatalytic removal of MG from aqueous solutions using TiO2-containing nanocomposites was reviewed. Methods: In this study, four databases (PubMed, Web of Science, ScienceDirect, and Scopus) were systematically searched to collect studies on the decomposition of MG using nanocomposites containing TiO2 under UV light radiation. Results: In total, 10 related and eligible studies were selected. Based on the results, TiO2 was doped with iron, Sn, Ag, Si, and Ni. The highest percentage of photocatalytic decomposition for MG was observed in Sn > Ni > Ag > Fe > Si. The removal efficiency of MG in the studied papers was between 75%-100%. Conclusion: Recombinant nanocomposites had a higher dye removal percentage than uncombined ones because they play an important role in the photocatalytic process of dye, by producing free radicals.

含二氧化钛的纳米复合材料光催化去除水溶液中的孔雀绿染料：系统综述

背景：孔雀绿（MG）在水产养殖业中被广泛用作杀菌剂、杀菌寄生剂、食品添加剂、医用消毒剂，以及丝绸、皮革、纸张等材料的染料。本研究综述了使用含TiO2的纳米复合材料光催化去除水溶液中的MG。方法：在本研究中，系统地检索了四个数据库（PubMed、Web of Science、ScienceDirect和Scopus），以收集关于在紫外线辐射下使用含有TiO2的纳米复合材料分解MG的研究。结果：总共选择了10项相关且符合条件的研究。结果表明，TiO2掺杂了铁、锡、银、硅和镍。Sn>Ni>Ag>Fe>Si对MG的光催化分解率最高。本文对MG的去除率在75%-100%之间。结论：重组纳米复合材料比未结合的纳米复合材料具有更高的染料去除率，因为它们通过产生自由基在染料的光催化过程中发挥着重要作用。
