In the present study, a high-strength food waste/fly ash/acrylamide composite hydrogel was developed by combining food waste and fly ash into functionalized particles using free radical cross-linking polymerization, with acrylamide used as the monomer, N, N′-methylene bisacrylamide as the cross-linking agent and sodium persulphate as the initiator. After one-factor experiments by changing the dosages of acrylamide, N, N′-methylene bisacrylamide, sodium persulphate, fly ash and polymerization temperature, the process conditions for the hydrogel to have the optimum mechanical property were obtained using response surface optimization. The experimental results showed that Young’s modulus of the produced hydrogels was as high as 2913 kPa at the dosages of acrylamide, N, N′-methylene bisacrylamide, sodium persulphate and fly ash of 4.349, 0.012, 0.540 and 1.181 g, respectively. Subsequently, the morphology and structure of the hydrogels were characterized using a Fourier transform infrared spectrometer, scanning electron microscope and X-ray diffractometer. The results showed that the interactions among polymer chains in the network structure of the hydrogel, the filling of fly ash and the hydrogen bonding combined to give the hydrogel excellent mechanical property. Meanwhile, Young’s modulus of composite hydrogel increased by 30.16% compared to that of the single-phase food waste hydrogel.</div>","PeriodicalId":502,"journal":{"name":"Bulletin of Materials Science","volume":"48 2","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143888757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study focuses on the removal of methylene blue (MB) dye using agricultural waste materials—tamarind seeds and rice husk. Among various dye removal methods, adsorption is found to be simple and effective. Activated carbon (AC) derived from tamarind seeds and rice husk was utilized as an economical adsorbent. The activated carbon from tamarind seeds was produced with a 500°C activation temperature and a 1:1 KOH:tamarind seed charcoal ratio, while the rice husk-based activated carbon was produced at 700°C with a 4:1 KOH:rice husk charcoal ratio. X-ray diffraction (XRD) analysis of tamarind seed-based activated carbon (ATSP) showed a peak at a 2θ value of 32.20°, confirming its crystalline structure. Batch adsorption experiments indicated that the adsorption capacities were 97.05% for activated tamarind seed powder (ATSP) and 89.11% for activated rice husk powder (ARHP). The mixed adsorbent of ATSP and ARHP achieved the highest dye removal efficiency of 95.27%. The adsorption behaviour and kinetics were analyzed using models such as the Langmuir, Freundlich, first-order kinetic model and second-order kinetic model. The Langmuir model exhibited the best alignment with the adsorption data, whereas the second-order kinetic model provided the most accurate description of the adsorption process. These results underscore the strong adsorption capabilities of tamarind seeds and rice husk, indicating their potential use in dye removal for wastewater treatment.

Biodiesel made from mixed oils by the transesterification process has tremendous prospects as an alternative fuel source. The quality and efficiency of biodiesel depend on the composition of the mixed oil. This paper focuses on optimizing the mixed oil ratio of the feedstock comprising waste cooking oil (WCO), jatropha oil (J) and karanja oil (K). The attributes of the manufactured biodiesel samples were examined against ASTM D6751 to determine its acceptability as a diesel alternative. Raw oils with free fatty acids (FFA) content exceeding 1% were pre-treated using the esterification method. After esterification, the FFA percentages of jatropha, karanja and waste cooking oil were reduced to 0.832, 1.75 and 0.467%, respectively. Transesterification is carried out at a temperature of 70°C by taking 1% (w/w) KOH as the catalyst for 2 h. Oil to methanol molar ratio was kept at 1:8. The biodiesel yield of the selected mixed oil ratios was approximately 91, 92 and 93%, respectively. These yields align closely with ASTM standards, highlighting the study’s effectiveness and significance. The ratio having a higher amount of jatropha (60:20:20) gave better results in terms of lower FFA content (0.07%), acid value (0.14%), cloud point (− 1°C), pour point (− 4°C), higher flash point (255°C) and fire point (260°C). In this case, the ratio with lower jatropha in it (20:60:20 J:K: WCO) showed better energy content due to its lower flash point (168°C) and fire point (175°C). This biodiesel production process generates minimal waste (primarily from the biodiesel washing stage) with the byproduct glycerin repurposed to make bioplastics and soap. Looking ahead, key directions in this study include developing ways for producing biodiesel from mixed oils utilizing effective catalysts in transesterification, presenting it as a sustainable alternative fuel to diesel.</div>","PeriodicalId":502,"journal":{"name":"Bulletin of Materials Science","volume":"48 2","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143835554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
