Key operational parameters such as initial Ni<sup>2+</sup> concentration, flow rate, catalyst mass, reactor volume, pH, and the number of catalytic plates were systematically investigated. A peristaltic pump facilitated the circulation of the solution under solar irradiation to enable the Ni<sup>+2</sup> reduction, a hazardous heavy metal. Experimentally, a maximum Ni<sup>2+</sup> reduction efficiency of 58 % was achieved at an optimal concentration of 20 ppm. The simulation results are very similar, predicting a reduction efficiency of 62 %. Such results demonstrate the potential of solar-driven photoreactors in treating heavy metal-contaminated wastewater and provides a basis for future optimization and scale-up studies.</div></div>","PeriodicalId":17276,"journal":{"name":"Journal of the Indian Chemical Society","volume":"102 8","pages":"Article 101872"},"PeriodicalIF":3.2,"publicationDate":"2025-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144523315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
