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...
متن کاملAmmonium 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 ...
متن کاملAdsorption behavior of cadmium on modified mesoporous aluminosilicates
In this study, mesoporous MCM-41 has been modified by incorporation of aluminum ion asa rapid, simple and inexpensive method for modification. The adsorbent is characterized usingpowder X-ray diffraction and nitrogen adsorption-desorption isotherm data. The distributioncoefficient of cadmium ion on the mesoporous aluminosilicates has been enhanced with theincrease of the aluminum in the framewo...
متن کاملHeavy metal adsorption by clinoptilolite from aqueous solutions
The present investigation has been carried out to assess a chromium, cobalt, and cadmium from wastewaters by natural and modified zeolites were examined by using batch type method. A clinoptilolite type synthetic / natural zeolite were pretreated with HCl and HNO3 to improve the adsorption capacity for heavy metals. The removal efficiencies and kinetics of heavy metals such as chromium, cobalt ...
متن کاملA solid-phase extraction method using Transcarpathian clinoptilolite for preconcentration of trace amounts of terbium in water samples
BACKGROUND In spite of the fact that terbium is one of the rarest elements in the Earth's crust, it is frequently used for the production of high technological materials. At the result, an effective combination of sample preparation procedure and detection method for terbium ions in different matrices is highly required. The solid-phase extraction procedure with natural Transcarpathian clinopti...
