Simultaneous removal of methylene blue and Cd(II) by pecan shell–based activated carbon: adsorption kinetics, isotherms, and physicochemical characterization

The coexistence of organic dyes and heavy metals in wastewater requires efficient and sustainable adsorbents capable of simultaneous contaminant removal. In this study, pecan shell–based activated carbons (PSC-0–PSC-3) were prepared by KOH activation using different impregnation...
