Abstract

Water pollution come from a number of different sources, and pollutants are divided up into various classes, such as organic pollutants, inorganic fertilizers, metals and radioactive isotopes. Organic pollutants are susceptible to biological degradation, unlike heavy metals which are not degrade into harmless products. Heavy metals are a common pollutant found in various industrial effluents. They are often encountered in mining operations and acid mine drainage. Because heavy metals are highly toxic and are non-biodegradable, therefore they must be removed from the polluted streams in order to meet increasingly stringent environmental quality standards. For this reason, in this paper it is presented research of removal of lead ions from acid aqueous solution using zeolite bearing tuff. The physical and chemical properties of the used natural material (zeolite bearing tuff) are characterized by x-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy and AES - ICP. In order to determine the effectivity of zeolite bearing tuff a series of experiments were performed under batch conditions from single ion solutions. Experiments were carried out at different initial ions concentration, different initial pH values and different adsorbent mass. The adsorption kinetics is reasonably fast. It means that in the first 20 min approximately 90% of Pb2+ is adsorbed from single ion solutions.
