Sustainable transformation of cotton stalk waste as a biochar-based copper-silicon composite for chromium (VI) detoxification

This study investigates the adsorption efficiency of a biochar composite derived from cotton stalks with copper and silicon (CSB-Si-Cu) for chromium (VI) removal from water. Characterization techniques, including XRD, FTIR, EDX, SEM, TEM, XPS, and PZC analysis, confirmed the material's structur...
