Rhodamine B (RhB) dye used in the textile industries is associated with carcinogenic and neurotoxic effects with a high potential to cause a variety of human diseases. Semiconductor photocatalysts synthesised through agriculture waste extracts exhibited high efficiency for RhB removal. The current review aimed to explore the efficiency and mechanism of RhB degradation using different photocatalysts that have been used in recent years, as well as the effect of various factors on the removal process. Zinc oxide nanoparticles (ZnO NPs) synthesised from plant extract is the most effective for the RhB degradation with the efficiency reaching 100% after 210 min. The photocatalysis process depends on the pH because pH changes the balance of water dissociation, which impacts the formation of hydroxyl radicals and the surface load of the catalyst. Analysis using Jupyter Notebook revealed a strong correlation between the concentration of ZnO NPs and the photocatalysis efficiency (R = 0.72). These findings reveal that man-sized photocatalysts have a high potential for removing RhB from the wastewater.
罗丹明 B（RhB）染料用于纺织工业，具有致癌和神经毒性作用，很可能导致多种人类疾病。通过农业废料提取物合成的半导体光催化剂对 RhB 的去除具有高效性。本综述旨在探讨近年来使用的不同光催化剂降解 RhB 的效率和机制，以及各种因素对去除过程的影响。植物提取物合成的氧化锌纳米颗粒（ZnO NPs）对 RhB 的降解最为有效，在 210 分钟后达到 100%的去除效率。光催化过程取决于 pH 值，因为 pH 值改变了水离解的平衡，从而影响了羟基自由基的形成和催化剂的表面负载。使用 Jupyter Notebook 进行的分析表明，ZnO NPs 的浓度与光催化效率之间存在很强的相关性（R = 0.72）。这些发现表明，人造光催化剂具有从废水中去除 RhB 的巨大潜力。
