Natural and Modified Clinoptilolite Testing for Reduction of Harmful Substance in Manufacturing Exploitation

Abstract

Polycyclic aromatic hydrocarbons are the component of the exhaust gases, from which some are characterized by carcinogenic and mutagenic properties. The most considerable sources of polycyclic aromatic hydrocarbons are combustion engines, thermal plants, production and distribution of products as pesticides, detergents, conservation matters, refuse inciferating plants, pyrolysis processes, coke production, cigarette gas, coal gasification. In consequence those matters from the atmosphere are accordied to earth, where they are cumulated, thereat bold increasing of aromatic hydrocarbons concentration is chronicled. The most dangerous from them is benzo(a)phyrene. If the polycyclic aromatic hydrocarbons are get into live organisms, reagents with their structure at formation epoxides and thiolepoxides. These matters liaise to DNA, corrupted their structure and this fact induces cancer formation. The sorption possibility of natural zeolite – clinoptilolite, also its modified forms was observed in regard to some species of polycyclic aromatic hydrocarbons.
