Also, the thermal characteristic of ZnCo₂O₄ nanoparticles was studied by thermogravimetric analysis (TGA). The capacity of ZnCo₂O₄ nanoparticles toward elimination of potentially toxic elements from aqueous media have been investigated by atomic absorption spectroscopy (AAS). The effect of various parameters including contact time, adsorbent mass, pH and initial metal concentration on the adsorption process have been investigated. Potentially toxic elements were removed using ZnCo₂O₄ nanoparticles, achieving maximum removal efficiencies of 92, 84, 60, and 50 % for Ni²⁺, Co²⁺, Cd²⁺, and Pb²⁺, respectively. A comparative analysis of linear and non-linear regression techniques for predicting optimal isotherms was conducted utilizing experimental adsorption equilibrium data. Various adsorption isotherm models, including Langmuir, Freundlich, Redlich-Peterson and Temkin were employed to analyze the experimental data. The findings indicated that the Langmuir equation provided a superior fit for the adsorption isotherms in the context of linear regression, whereas the Redlich-Peterson model demonstrated better fitting in non-linear regression. Kinetic modeling revealed that non-linear pseudo-second-order and Elovich models best describe the adsorption behavior of potentially toxic metal ions onto ZnCo₂O₄ nanoparticles, with contributions from both chemisorption and intraparticle diffusion mechanisms.</div></div>","PeriodicalId":17276,"journal":{"name":"Journal of the Indian Chemical Society","volume":"102 9","pages":"Article 101907"},"PeriodicalIF":3.2,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144604719","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}

Inspired by this, a series of quinazolin-4(3<em>H</em>)-one and benzenesulfonamide hybrids were synthesized and evaluated for their antiproliferative and cytotoxic activities using human non-small cell lung (A549), human liver (HepG2), and human breast (MCF-7) cancer cell lines, as well as a normal human lung fibroblast (CCD-34) cell line in this study.

According to the biological activity results, a significant number of compounds with strong antiproliferative activity against various cancer cell lines, along with an acceptable selectivity rate, were identified.
