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.

利用环保氧化铜纳米粒子和氧化铁纳米棒去除实际纺织工业废水中的染料

被染料废水污染的纺织工业废水构成了重大的环境挑战。许多纳米粒子被用作吸附剂来处理类似的刺激废水，但特别是通过绿色方法合成的纳米材料已经引起了人们的关注。为了评估它们在解决现实世界纺织废水污染方面的实际适用性，建议对真实纺织工业废水中的染料去除进行研究。因此，开展了一项针对实际纺织工业废水中染料去除的研究，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。该研究仔细研究了吸附剂用量、吸附剂-吸附物接触时间和废水 pH 值对染料吸附百分比的影响。这些发现表明，增加吸附剂剂量和接触时间会导致更高的染料去除百分比。值得注意的是，氧化铜纳米颗粒在 pH 值 5 和 7 时表现出优异的染料去除效率，超过了氧化铁纳米棒在 pH 值 12 时的最大染料去除效率。该研究实现了氧化铜纳米颗粒 95.24% 和铁 62.5% 的令人印象深刻的工艺效率氧化物纳米棒。采用响应面法 (RSM) 进行统计数据分析和优化染料去除工艺参数，以最大限度地提高效率。总的来说，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有前途且有效的解决方案。
