Development of eco-friendly activated carbon from olive pits for the adsorption of tartrazine with isotherm kinetic and thermodynamic studies (opens in new tab)

Synthetic dyes discharged into water bodies pose a persistent environmental threat owing to their resistance to natural degradation, toxicity, and long-term ecological impact. In this study, discarded olive pits were valorized as a lignocellulosic precursor for the production of activated carbon through phosphoric acid activation. Multiple analytical tools including pHpzc, FTIR, SEM, XPS, and XRD—were used to examine the structural, physicochemical, and morphological characteristics of the pr...
