Adsorption of Enrofloxacine on Natural Zeolite - Clinoptilolite

The potential use of Croatian natural zeolite clinoptilolite as alternative adsorbents for removal of enrofloxacin (ENRO) as model pollutant was studied in a batch system. The influence of contact time and initial ENRO concentration on the sorption process was investigated. The percentage removal of ENRO from aqueous phase decreased with an increase in initial concentration. The experimental da...

Studies of Adsorption from Gaseous and Liquid Mixtures on Solids of Quasi-Gaussian Energy Distribution

Previous research69 has shown that the Toth equation describes well the adsorption of hydrocarbons on carbon adsorbents, especially on Nuxit-Al charcoal. This fact is probably connected with the quasi-gaussian energy distribution function, which is related to T6th's equation. In this paper, the parameters of the above mentioned equation have been discussed once again and recent results on this ...

Multilayer adsorption and wetting of acetone on graphite.

Adsorption/desorption isotherms of acetone on highly oriented pyrolytic graphite have been measured by ellipsometry for temperatures above the bulk triple point. The behavior in the monolayer and submonolayer regime is conventional, with 2D gas-liquid and 2D liquid-solid coexistence regions. Further liquid monolayers grow on top of the completed monolayer. The growth is basically layer-by-layer...

Ammonium Adsorption on Natural Zeolite (clinoptilolite): Adsorption Isotherms and Kinetics Modeling

A batch sorption process for removal of ammonium ions from aqueous solution using natural zeolite was studied. Tree different particle sizes of zeolite (1-2 mm, 2-4 mm and 4-10 mm) were used in the experiments. Sorption of ammonium ions on natural zeolite were carried out at 298 K with the initial concentrations of ammonium in the range of 1000 – 7000 mg NH4 -N/dm. Equilibrium data were fitted ...
