Arsenic contamination in water poses a significant threat to the environment and human health due high toxicity of arsenic. Therefore, development functionalized materials with an enhanced adsorption capacity for arsenic remains key research focus purification. In this study, straw powder was hydrothermally pretreated subsequently pyrolyzed zinc chloride at 700 °C produce hydrothermal biochar tailored pores. The then modified sulfhydryl groups, Sulfhydryl-Modified Biochar/MgFe-Layered Double Hydroxides (SH@HB/MgFe-LDH) composites were synthesized using coprecipitation method. By utilizing HB surface area, composite material specific area 479.3677 m2/g prepared. experimental results indicated that SH@HB/MgFe-LDH exhibited excellent performance across wide pH range, achieving as 388.01 mg/g. process mechanism investigated through kinetics, isotherms, thermodynamic analysis, X-ray photoelectron spectroscopy. Additionally, recycling studies demonstrated maintained stable over three reuse cycles, showing good potential practical applications. Overall, offer effective solution pollution control while promoting high-value utilization agricultural forestry waste.

The search for sustainable and efficient remediation techniques is required to control increasing environmental pollution caused by synthetic dyes, heavy metal ions, other harmful pollutants. From this point of view, natural polymers like chitosan, cellulose, lignin, pectin have been found highly promising due their biodegradability, availability, possibility chemical functionalization. Natural possess inherent adsorption properties that can be further enhanced cross-linking surface activation. This review discusses the main properties, mechanisms, functional groups such as hydroxyl, carboxyl, amino responsible pollutant sequestration. paper also emphasizes effectiveness in removing metals dyes from wastewater recent advances polymer modifications, including ionic crosslinking grafting. study underlines ecological potential polymer-based adsorbents treatment protection environment a solution challenges.
