文摘

Zeolite–activated carbon (Z–AC) composite was synthesized with oil palm ash as precursor. The adsorption process was well supported by kinetic and isothermal models. The adsorption capacity of Z–AC for MB was superior to similar types of adsorbents. The Z–AC composite represents low-cost composites as adsorbents for dye removal.
