Recent advancements in environmental technology have led to the development of a novel biocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More made from date palm kernels, offering a breakthrough solution for the purification of water contaminated with industrial dyes. This innovative material, known as Date Palm Kernel Biochar-Sulfur (DPKB-S), has been meticulously analyzed and proven highly effective in adsorbing Methylene Blue (MB) dye, a prevalent contaminant in wastewater.

Through detailed examinations including BET, BJH, FT-IR, SEM, EDX, DSC, and TGA analyses, DPKB-S demonstrated outstanding properties for dye adsorption, achieving a 100% removal rate under optimal conditions. This efficiency was observed at an adsorbent concentration of 0.75 g L−1 and a dye concentration of 50 ppm, highlighting the material’s potential for real-world application. The adsorption process was further explored through the Langmuir and Freundlich isotherm models, revealing insights into the mechanism and dynamics of dye removal at varying concentrations.

The kinetic analysis, supported by a pseudo-second-order rate model, underscores the adsorption process’s efficiency, suggesting that DPKB-S could serve as a cost-effective and environmentally friendly solution for wastewater treatment. This study not only contributes to the field of environmental science but also emphasizes the importance of utilizing sustainable materials like biochar for water purification, aligning with global efforts towards pollution reduction and environmental preservation.
