An easy co-precipitation technique was used in this work to create the VNi-layered double hydroxide (VNi-LDH) adsorbent. VNi-LDH was encapsulated with chitosan (CS) and carboxymethyl cellulose (CMC) that cross-linked with itaconic acid as the cross linker via chemical crosslinking to form VNi-LDH/CS-CMC hydrogel beads. FT-IR, SEM, XPS, BET, XRD, BET, and point of zero charge (pHzpc) were employed to characterize the prepared material. Examining VNi-LDH/CS-CMC's ability to remove rhodamine B (RB) from water waste as an adsorbent was the aim of the study. The highest adsorption capacity of RB on VNi-LDH/CS-CMC was found to be 653.8 mg/g. The research findings designated that the Langmuir isotherm models provided the most accurate representation of the RB adsorption procedure for VNi-LDH/CS-CMC. At a dosage of 0.8 g/L for the adsorbent and an equilibrium time of 100 min, it was established that the RB adsorption of VNi-LDH/CS-CMC hydrogel beads occurred at a pH of 8. The model of pseudo-second order, demonstrating chemisorption with an adsorption energy of 30.34 kJ/mol along with a diffusion-limited adsorption process, was most appropriate for the RB adsorption kinetics on VNi-LDH/CS-CMC hydrogel beads. The impact of temperature was also investigated, with an analysis of the thermodynamic variables (∆<i>H</i>°, ∆<i>S</i>°, and ∆<i>G</i>°) revealing a spontaneous increase in positive enthalpy and entropy charge, along with a decrease in Δ<i>G</i>°, as the temperature rose. The adsorption process outcomes were further optimized using response surface methodology (RSM) and the Box–Behnken design (BBD). It was proposed that the elimination of RB through VNi-LDH/CS-CMC may occur through different potential mechanisms, such as chemisorption, pore-filling, π-π bonding, electrostatic interactions, and hydrogen bonding. Given that the adsorbent was made of reusable materials and could be reused more than six times with high efficiency, the VNi-LDH/CS-CMC hydrogel beads offer a viable low-cost option for removing RB dye from wastewater streams.</p>\u0000 </div>","PeriodicalId":8344,"journal":{"name":"Applied Organometallic Chemistry","volume":"39 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142868381","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
