The LDHs before and after adsorption were thoroughly characterized using SEM, XRD, FTIR, BET surface area analysis, XPS, and zeta potential measurements. The results demonstrated that hydrothermally synthesized Mg/Al-LDHs exhibited enhanced structural ordering and superior crystallinity, as evidenced by sharp and intense XRD peaks and increased BET surface area, and higher adsorption capacities, 240 mg/g for Cu(II), 512 mg/g for Pb(II), and 484 mg/g for Cr(VI), achieving equilibrium within 60 min. Adsorption kinetics followed a pseudo-second-order model, and equilibrium data were best described by the Langmuir isotherm, indicating a monolayer chemisorption process. In contrast, the in situ synthesis method proved advantageous in operational simplicity and reagent efficiency, achieving 100 % Pb(II) and >80 % Cu(II) and Cr(VI) removal under alkaline conditions. Mechanistic analysis suggested that adsorption involved surface complexation, ion exchange, and surface precipitation. Furthermore, the adsorption of Cu(II) was only marginally affected by changes in pH, with a slight increase in capacity observed at higher pH levels. In contrast, Pb(II) showed a pronounced rise in adsorption with increasing pH, while Cr(VI) displayed the opposite behavior, with its adsorption decreasing as pH increased. These results demonstrate that optimizing LDH mineral structure enhances heavy metal uptake through improved stability and surface reactivity, supporting the development of high-performance, reusable adsorbents for sustainable wastewater remediation.</div></div>","PeriodicalId":17276,"journal":{"name":"Journal of the Indian Chemical Society","volume":"102 11","pages":"Article 102088"},"PeriodicalIF":3.4,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145004968","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}

Nowadays, these enzymes are utilized as one of the main ingredients by the industries for manufacturing products and some environmental researchers exploit it for biodegradation studies. The present study highlights the unique biodegradation potential of Halobacillus trueperi RRJS1, a halophilic bacterium capable of producing highly active alkaline protease enzyme. It can withstand high salinity and can survive osmotic stress in the extreme salt concentration. Generally, halophiles produce more extracellular enzymes in high salt concentrations which are generally called as halozymes. Halophiles are salt loving bacteria that thrive in salt lakes and they are competent to produce more extracellular enzymes. These enzymes remain stable under these conditions. In the present research, the halophilic bacteria <em>H. trueperi</em> RRJS1 is screened for production of alkaline protease enzyme and it was used for the degradation of highly toxic ingredients found in the textile azo dye effluent. The bacterial strain <em>H. trueperi</em> RRJS1 was optimized with various physico - chemical parameters and maximum production of the alkaline protease enzyme was recorded at 40 °C and pH 7.5 (99.23 ± 0.42 U/ml); and in 6 % NaCl concentration (60.5 ± 1.28 U/ml).
