Clinoptilolite

Clinoptilolite is a natural zeolite with exceptional adsorption capacity. Integrated into an appropriate technical set-up it has been tested with raw-water mimicking the situation in emergencies where the requirement of safe drinking water has been critical for the public health. These results have

This study was performed to evaluate the physicochemical properties of dissolved organic carbons (DOC) in the effluents coming from a clinoptilolite amended activated sludge with regard to various sludge retention times (SRTs) singularly run or in combination with a coagulation process. First, four

Adsorption techniques are widely used to remove certain classes of pollutants from waters, especially those that are not easily biodegradable. Dyes represent one of the problematic groups. Natural zeolite was used as a low-cost adsorbent to evaluate its ability to remove color from effluents. In thi

Zeolites are naturally occurring minerals characterized by high cation exchange and adsorption capacity and, thus, are used for metal uptake from sewage sludge subjected to composting process. In the present paper, changes in the physicochemical characteristics of sewage sludge samples after compost

Clinoptilolite, a natural zeolite, was used for the synthesis of a high surface area clinoptilolite-iron oxide system (Clin–Fe system) to be used for the removal of Mn2+ and Zn2+ ions from drinking water samples. The new system was obtained by adding natural clinoptilolite to an iron nitrate solutio

The ability of natural zeolite (clinoptilolite) and exfoliated vermiculite to remove copper from aqueous solutions was studied in fixed bed column and batch reactors. The effect of agitation speed (0, 100, 200, 400 rpm), temperature (25, 45, 60°C), and particle size [2.5-5.0 mm, dust ( clinoptilolit

In the present study, the ability of natural zeolite clinoptilolite and bentonite (clay) to remove Pb(II) from aqueous solutions has been investigated in batch reactors with a maximum contact time of 120 min. Adsorption tests of Pb(II) were carried out using a solution concentration of 1,036 ppm at

Zeolite was used as a low-cost adsorbent to evaluate its ability to remove color from textile effluents. The zeolite (clinoptilolite) used in this study is a natural clay mineral from the Gördes region of Turkey. The adsorption of reactive dyes into zeolite was investigated by a series of batch adso
