This research aims to evaluate the adsorption capacity of modified activated carbon from date pits for removing cationic and anionic dyes from wastewater.
Batch adsorption studies were conducted to optimize parameters such as pH, initial concentration, adsorbent dose, time, and temperature.
Adsorption isotherm and kinetic models were used to analyze the interaction and mechanism of dye adsorption.
Maximum uptake of methylene blue was 833 mg g −1 at pH 5.5-10 and 743 mg g −1 for Congo red at pH 2-4.5.
The pseudo-second-order model fit the kinetic data best, suggesting chemisorption involvement.
