Dyes are one of the most important existing pollutants in textile industrial wastewater. These compounds are often toxic, carcinogenic, and mutagenic to living organisms, chemically and photochemically stable, and non-biodegradable. Acid red 18 is one of the azo dyes that are currently used in the textile industries. Photocatalytic degradation offers a great potential as an advanced oxidation process, in this study photocatalytic degradation of Acid red 18 by using BiOI/ZnO nanocomposite was evaluated under visible light irradiation. The influence of most essential parameters such as pH and BiOI/ZnO dosage were studied for optimum conditions. The dye removal efficiency was 85.1% at optimum experimental conditions of pH of 7, and BiOI/ZnO dosage of 1.5 g/L. The data had a good agreement with pseudo first-order kinetic model. Thus, the BiOI/ZnO/UV is an efficient process for dye degradation.
染料是纺织工业废水中现存的最重要污染物之一。这些化合物通常对生物体有毒、致癌且具有致突变性，化学和光化学性质稳定，且不可生物降解。酸性红18是目前纺织工业中使用的偶氮染料之一。光催化降解作为一种高级氧化工艺具有很大潜力，本研究在可见光照射下评估了BiOI/ZnO纳米复合材料对酸性红18的光催化降解。研究了诸如pH值和BiOI/ZnO用量等最关键参数对最佳条件的影响。在pH值为7、BiOI/ZnO用量为1.5 g/L的最佳实验条件下，染料去除率为85.1%。数据与准一级动力学模型吻合良好。因此，BiOI/ZnO/UV是一种高效的染料降解工艺。
