The content of each sample was brought to the mark with distilled water and a sample of natural zeolite in the weight of 2 g was added to the container
Summary
Heavy metals (mercury, lead, cadmium, zinc, copper, chromium, arsenic) belong to widely spread and highly toxic contaminants. They are commonly used in various industrial enterprises; despite the treatment measures, the content of heavy metal compounds in industrial wastewater is quite high (Han et al 2009). In the areas contaminated by industrial waters, their concentration in solutions and suspensions increases extremely (Sabadash et al 2017, Ates et al 2016). These are emissions from the industrial and domestic effluents, from the smoke and dust of industrial plants, especially galvanic ones, with the exhaust gases of internal combustion engines. Since all heavy metals are highly toxic and MPC averages about 0,1 mg/l, it is advisable to use the sorption methods to clean up such effluents, which allow trace amounts of contamination to be extracted (Wang et al 2007, Kithome et al 1999)
