摘要

受染料废水污染的纺织业废水对环境构成了巨大挑战。许多纳米粒子被用作吸附剂来处理类似的废水,但通过绿色方法合成的纳米材料尤其受到重视。为了评估纳米材料在解决现实世界纺织废水污染中的实际应用性,建议对真实纺织工业废水中的染料去除进行研究。因此,我们开展了一项以去除真实纺织工业废水中的染料为重点的研究,并选择生物合成的氧化铜纳米颗粒和氧化铁纳米棒作为吸附剂。调查仔细研究了吸附剂用量、吸附剂-吸附剂接触时间和废水 pH 值对染料吸附率的影响。这些研究结果表明,增加吸附剂用量和接触时间可提高染料去除率。值得注意的是,纳米氧化铜颗粒在 pH 值为 5 和 7 时表现出更高的染料去除效率,超过了纳米氧化铁颗粒在 pH 值为 12 时的最大染料去除效率。 该研究发现,纳米氧化铜颗粒和纳米氧化铁颗粒的工艺效率分别达到了 95.24% 和 62.5%。研究采用响应面方法(RSM)进行数据统计分析,并优化染料去除工艺参数,以最大限度地提高效率。总之,研究结果表明,生物合成纳米材料为去除纺织工业废水中的染料提供了一种前景广阔的有效解决方案。

Utilization of Eco‐friendly Copper Oxide Nanoparticles and Iron Oxide Nanorods in Dye Removal from Real Textile Industry Effluent

Utilization of Eco‐friendly Copper Oxide Nanoparticles and Iron Oxide Nanorods in Dye Removal from Real Textile Industry Effluent
Textile industry wastewater contaminated with dye effluents poses a significant environmental challenge. Numerous nanoparticles are used as adsorbents to treat similarly stimulated wastewater, but particularly nanomaterials synthesized through green methods have gained prominence. To assess their practical applicability in addressing real‐world textile wastewater pollution, studies on dye removal from authentic textile industrial effluents are recommended. As a result, a study focused on the removal of dye from real textile industrial effluent is conducted, and biosynthesized copper oxide nanoparticles and iron oxide nanorods are chosen as adsorbents. The investigation scrutinized the influence of adsorbent dosage, adsorbent‐adsorbate contact time, and wastewater pH on the percentage of dye adsorption. These findings indicate that increasing the adsorbent dosage and contact time leads to a higher percentage of dye removal. Notably, copper oxide nanoparticles exhibit superior dye removal efficiency at pH levels 5 and 7, outperforming the maximum dye removal efficiency of iron oxide nanorods at pH 12. The study achieved an impressive process efficiency of 95.24% for copper oxide nanoparticles and 62.5% for iron oxide nanorods. Response surface methodology (RSM) is employed for statistical data analysis and optimization of dye removal process parameters to maximize efficiency. Overall, the results demonstrate that biosynthesized nanomaterials offer a promising and effective solution for removing dyes from textile industrial wastewater.
