Summary: Surface chemical modification allows for the rational construction of biochar with desirable structures and functionalities for environment purification. Fruit-peel-derived adsorbing material has been well studied in the adsorption of heavy-metal removal due to its abundance and non-toxicity. In this study, engineered biochar prepared from fruit waste via chemical modification was explored for its potential application in removing chromium (Cr) from an aqueous solution.

Summary: This study modified bagasse with phosphoric acid, nitric acid, and oxalic acid to obtain PMB, NMB, and OMB adsorbents for Cr(VI) adsorption in wastewater. An orthogonal test was conducted to investigate the effects of immersion ratio, immersion temperature, immersion time, and acid concentration on the adsorption performance. The results showed that the adsorbent had the highest adsorption efficiency under specific conditions. Characterization analysis revealed that the surface properties of PMB, NMB, and OMB differed from those of bagasse, and they exhibited better adsorption performance than the original bagasse. Langmuir adsorption isotherm and quasi-secondary kinetic equation confirmed the adsorption of Cr(VI) by PMB, NMB, and OMB. Overall, PMB, NMB, and OMB can effectively purify Cr(VI) wastewater.

Summary: Hydrocalumite (HC) is developed as a promising adsorbent for chromium removal, but its powder form limits its practical application. In this study, HC was dispersed in biopolymeric matrices (chitosan and cellulose) to form hybrid bio-composites (HCCS and HCCel) for Cr(VI) removal. Magnetic bio-composites (Fe3O4@HCCS and Fe3O4@HCCel) were prepared for easy separation after adsorption. The synthesized bio-composites showed high adsorption capacity and can be regenerated up to four times with NaOH solution. They are efficient adsorbents for chromium removal.

Summary: Nitenpyram (NIT), the most water-soluble neonicotinoid, has been shown to pose a serious threat to human health and the environment. In this study, two types of biochar, ZBC and KBC, were activated using different methods and their adsorption performance for NIT was compared. The results indicated that KBC had better adsorption performance than ZBC, with a small amount of KBC being able to efficiently absorb NIT. The removal rates of NIT were influenced by its initial concentration and the dose of biochar, and were not affected by pH but inhibited by salt ions.

Summary: Cellulose hydrogels were fabricated using LiCl/dimethylacetamide as a new method and investigated for their ability to remove DB86 dye from water. The hydrogel was characterized by FTIR, XRD, SEM, and TGA analyses. The optimum pH for dye absorption was found to be 2, and the Temkin model best fit the absorption results of the hydrogel. Kinetic absorption studies showed that the pseudo-second-order model had the highest R-2 value, indicating strong control over the absorption rate. These findings suggest that cellulose hydrogels have potential for DB86 dye removal from wastewater.
