In the last years, modified ash has been researched for a variety of agricultural and environmental applications. Modified ash can is used as soil conditioners, amendments, remediation agents in contaminated soils with heavy metal ions. In this paper, the different methods modification of ash with KOH was studied. Ash from thermal power plant and modified ash were used for removal of heavy metal ions from soil. The ash and the modified ash were characterized by microstructure (electronic microscopy SEM), chemical and mineralogical composition (EDAX, XRD diffraction, FTIR). According to the XRD results, it was proven that the form of modified ash was K-chabazite. The determination removal capacity of heavy metals ions from soil was performed by atomic absorption.
