The present paper describes the previous obtained results concerning purification of gases, water and sewages from toxic components such as mercury, radionuclides and petroleum substances. The tested materials constitute synthetic zeolites obtained in hydrothermal reaction, i.e., Na-X, Na-P1, and natural zeolite clinoptilolite. The zeolites (Na-X, Na-P1 and clinoptilolite) needed for mercury ca...

The Serbian natural zeolite is moderately effective in removing the zinc(II) ions from aqueous solutions. At 298 K the sorption capacity varies from 13 to 26% for the initial Zn(II) solution concentration of 100 and 600 mg Zndm(-3), respectively. The sorption isotherm at 298-338 K is best represented by the Langmuir model and the sorption kinetics by the pseudo-second-order model. The sorption ...

INTRODUCTION zeolites (clinoptilolites) are a family of alluminosilicates and cations clustered to form macro aggregates by small individual cavities. In the medical area they are involved in detoxification mechanisms capturing ions and molecules into their holes. Actually, we classify about 140 types of natural and 150 synthetic zeolites, for specific and selective use. Clinoptilolite is a nat...

a total of 448 ross 308 seven-day old male broiler chicks were assigned to seven treatments with four replicates, each containing 16 chicks, to determine effects of physical sizes and rate of dietary inclusion of clinoptilolite. the chicks fed diet containing clinoptilolite at 1.5% and particle size of 0.4-0.8 mm showed significantly higher body weight gain than the control group that did not r...

In the present study a practical model useful for designers dealing with pilot scale reactors for pollutant control has been developed. Investigations were undertaken for a single-component lead study on New Zealand clinoptilolite at the temperature of 25+/-1 degrees C. Fifteen runs under different operating conditions such as particle characteristics (expressed as d*(p)/D), column geometry (as...

The Gibbs energy changes for the reaction between copper, cadmium, and lead ions complexes with gallic acid clinoptilolite containing single-charged (Na, K) double-charged (Ca, Mg) exchange were calculated. software PRIRODA PBE/3ζ theoretical method has been used these calculations:
 (GalAn)2X×2H2O + Clin-Me 2H3O+ → X(H2O)n-Clin 2GalAn– (6-n)H2O 2Me+(Me2+).

a nanocomposite of polyaniline (pani) with natural clinoptilolite (clino) was prepared by chemical oxidative polymerization of anilinium cations in the presence of clinoptilolite dispersion. the pani/clino nanocomposite was characterized using ftir, xrd and sem techniques as well as electrical conductivity measurement using four point probe technique. cyclic voltammetry analysis was used to inv...
