Abstract

The aim of study was to reduce chemical contaminant from water and wastewater by adopting low-cost adsorption process over modified fly ash, which prepared easily by two methods, alkaline added under hydrothermal conditions, some physio-chemical technique used to characterize the modified fly ash as XRF, XRD, BET technique and scanning electron microscopy SEM. The result showed that the modified fly ash has crystal structure hexagonal and it attributed to zeolite A, the regarding of crystal structure, specific surface area and external morphology examined by SEM, the estimation of specific surface area affiliated to type (IIB) isotherm which is similar to non-porous or macroporous materials, finding results showed that the modified fly ash described better to both Freundlich and Langmuir model isotherm for removal mechanism, the maximum adsorption capacity q_max for Zn²⁺ an Fe²⁺ is 114.2 and 196.7 mg/L respectively, furthermore, iron and zinc ions removed well by direct method SZ1 due to the crystal lattice structure, big surface area and pore size 49.317 and 38.813 m²/g respectively, finally modified fly ash can be used as low-cost adsorption material due to the nature of ion- exchange and performance in adsorption according to their big surface area.
