Adsorption of heavy metals in mine wastewater by

01/01/2012  Mongolian natural zeolites could adsorb and remove copper, zinc, and manganese in the aqueous solutions. The precipitation of metal hydroxide affected the results of adsorption in some cases. The saturated adsorbed amounts of the heavy metals estimated by Langmuir equation were almost same with one another, increased with solution pH and with cation exchange capacity of the natural zeolite ...

Effect of Modification of Mongolian Natural Zeolites on ...

Removal of chromium (Cr (III) ) as well as hexavalent chromium (Cr (VI) ) from tannery wastewater at same time by adsorption using Mongolian natural zeolite was studied in terms of the characteristics, modification, and chromium adsorption performance of the zeolite. The cation exchange capacity of the zeolite ranged from 37×10−3 to 144×10−3 eqg−1. From the results of phase ...

20/10/2008  We applied Mongolian natural zeolite to adsorptive removal of hexavalent chromium contained in tannery wastewater. At first, characterization was carried out for various kinds of natural zeolites obtained from Tsagaan Tsav and Urgon deposits in Dornogovi province, southeast part of Mongolia. From the X-ray diffractometry analysis, the zeolite samples were composed of mordenite,

In the first, Mongolian natural zeolites, whose base components were clinoptilolite, mordenite, and chabazite, were characterized in terms of element content, cation exchange capacity, and the like. Since the molar ratios of aluminum relative to silicon contained in Mongolian natural zeolites used in this study were lower than those of pure zeolites, the natural zeolite samples contained ...

15/05/2019  When natural zeolites are added to concrete, the compressive strength of concrete can be reduced owing to the high amount of mixing water required by the porous structure and the high surface area of natural zeolites [20,21,41,43]. Furthermore, the reduction in compressive strength is also attributed to the water/cement (w/c) ratio. For example, it has been insisted that the compressive ...
