چکیده
In this study, the suitability of zeolite as a possible medium for ammonium adsorption, desorption and recovery from wastewater was investigated. Specifically, batch adsorption studies with solutions enriched in NH$_4^+$ were conducted employing to evaluate how chemical treatment contact time affect desorption. Several experimental tests carried out considering both untreated treated zeolite. Untreated HCl-Na adsorbed up 11.8 mg g$^{-1}$ showed highest efficiency recovering aqueous solution. Regardless pre-treatment, treatments NaCl resulted higher faster than CaCl$_2$ MgCl$_2$.

The effective management of sewage sludge materials in an environmentally and economically acceptable way is through the pyrolytic conversion of the sludge to biochar and its use for agricultural purposes. The aims of this work were: (1) to assess the effect of biochar prepared from sewage sludge at two different temperatures (350 ºC and 650 ºC) on the adsorption/desorptio...
متن کاملAdsorption characteristics of ammonium ion by zeolite 13X.
With synthetic wastewater, lab-scale batch experiments and column experiments were carried out to investigate the adsorption characteristics of ammonium ion by zeolite 13X which is a hydrothermally synthetic byproduct accompanied with preparation of potassium carbonate from insoluble potash ores. The Langmuir and Freundlich models were applied to describe the equilibrium isotherms for ammonium ...

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 and desorption of ammonium by maple wood biochar as a function of oxidation and pH.
The objective of this work was to investigate the retention mechanisms of ammonium in aqueous solution by using progressively oxidized maple wood biochar at different pH values. Hydrogen peroxide was used to oxidize the biochar to pH values ranging from 8.1 to 3.7, with one set being adjusted to a pH of 7 afterwards. Oxidizing the biochars at their lowered pH did not increase their ability to a...

A well-defined cluster containing 12 equivalent platinum atoms was prepared by ion exchange of an NaY zeolite, followed by hydrogen reduction. It was characterized by electron paramagnetic resonance (EPR) spectroscopy, hyperfine sublevel correlation (HYSCORE), and theoretical calculations. Combing the results of the experiments with density functional calculations, the likely structure of this ...
