Preparation of Adsorbent from Fly Ash for Methylene Blue Wastewater Treatment
Fly ash contains SiO2 and Al2O3,which account for more than 60%of the total.This is similar to the composition of zeolite which is frequently be used for adsorbent.Therefore,fly ash is used to prepare adsorbent for wastewater treatment by microwave-assisted hydrothermal method.The optimal reaction conditions were determined: alkali-ash ratio of 15:1,reaction temperature of 100℃ and reaction time of 0.5h.The removal rate of methylene blue is up to 97.6%.The adsorbent was characterized by SEM and FT-IR.Large number of silicon(aluminum)oxygen tetrahedrons and the porous lattice structure contribute high adsorption performance of the adsorbent.
