In the current work, polyacrylic acid and bio-polymer-based hydrogels of hydroxyl ethyl cellulose (HEC) were prepared through the free radical polymerization method and were used as adsorbents for the adsorption of methylene blue (MB). To estimate the nature and mechanism of adsorption, kinetics, and isotherm models were adopted. Pseudo-second-order kinetic model was followed by the sorption of MB. Results demonstrated that with an increase in concentration of dye dosage, adsorption increases linearly. Freundlich isotherm model was followed for the sorption of MB onto polyacrylic acid and bio-polymer-based hydrogels. Thermodynamic study of the adsorption process reveals that the adsorption process was spontaneous and endothermic as inferred from Gibbs free energy and enthalpy values of 33.08 kJ/mol and 3.83 kJ/mol at 303K, respectively. Recycling performance was tested and inferred that bio-polymer-based hydrogel having 0.6 gm. Hydroxyethyl cellulose decreases its adsorption efficiency equivalent to 5% after consecutive five cycles. The bio-polymer-based hydrogels will be used as an effective adsorbent for removing cationic dyes from wastewater on an industrial scale.","PeriodicalId":21680,"journal":{"name":"Separation Science and Technology","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2023-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139262067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, pellet form is needed for industrial application. In this study, shaped zeolite X (ZX) and Fe3+ ion-exchanged zeolite X (ZXFe) with geopolymer as binder were produced in forms of cylinder pellets (Ø = 5 mm, h = 5 mm) at low temperature. The geopolymer was obtained through the geopolymerization of metakaolin using NaOH as an alkaline activating agent. The material formed by this way remained the zeolite X structure that was confirmed by X-ray diffraction (XRD) analysis. Additionally, scanning electron microscopy (SEM) results of the two different kind geopolymer – zeolite pellets were considered for observation and comparison. BET analysis was also conducted to determine the specific surface area of the GZX3 samples and GZXFeL3 samples. This kind of analysis also provided the information about the adsorption – desorption curves and pore size distributions of the two pellet samples. The difference of the temperature in the pretreatment process affected the degas ability of the pellet and the series of experiments were carried out to make clear comparison. The highest CO2 adsorption capacities of pellets were found in the GZX3 (containing the zeolite X) and GZXFeL3 (containing the ZXFe). Despite the rapid decrease in the surface areas from 409 to 261 m2/g for GZX3 and GZXFeL3 respectively, GZXFeL3 showed higher CO2 capacities than the other (1.03 compared to 0.96 mmol/g). In the regeneration study, after several cycles of adsorption – desorption of GZXFeL3 pellets, the adsorption capacity of CO2 decreased about 10%. These adsorption and desorption experiments implied that the pellets formed by ZXFe could be a promising adsorbent for the CO2 capture.","PeriodicalId":21680,"journal":{"name":"Separation Science and Technology","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2023-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139269146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
