Summary:The article suggests the usage of ash from sunflower husk combustion, which is constantly considered to be production waste, as a treating agent for electroplating industry wastewater purification. The chemical and mineral composition of ash waste has been researched by means of X-ray diffraction method with an X-ray fluorescent spectrometer. The structure of waste has been studied with a high-resolution scanning electron microscope. The ash contains calcium, magnesium and potassium oxides, so this waste can be used as a chemical treating agent in purifying water from heavy metals. The acid leaching of ash has been performed to determine the degree of its components transition. The trial purification of real electroplating wastes with the ash has been carried out. The purification efficiency for nickel and copper amounts to 62.0 and 48.0 % at the ash consumption 3.0 g/dm3.
