zeolites due to their structures can be used as molecular sieves for purification of materials and solutions. zeolites with phi and sod structure are so common and applicable for this purpose. hydroxy sodalite and phillipsite are the more abundant members of zeolites which display good selectivity for very small molecules and some ions such as sr, pb, zn, cu and rb. there is not any pure natura...

In this study, Response Surface Methodology (RSM) using Central Composite Design (CCD) was employed to optimize the conditions of independent variables (adsorption time and ion solution concentration) for the removal of Zinc (II) and Ag ions from the aqueous solutions using analcime and modified analcime zeolites (Fe-ANA and Ni-ANA) as efficient and low cost adsor...

In this article, we have investigated the role of dimethylamine (DMA), tributylamine (TBA), Triethanoleamine (TEA), Trishydroxymethylamine (TRIZMA), and Hexamethyleneterraamine (HMTA), in the formation of zeolitic compounds. The experiments were carried out in acidic and basic media using Si/Al< 10 and Si/A1>10. The structure of the resulting synthetic zeolites were similar to Natro Davyne,...

This work describes a valorization procedure for one of the most important wastes generated during aluminum recycling, namely, saline slag. was divided in two steps: a) recovery or its compounds various fractions, and b) use those fractions synthesis zeolites: analcime (NaAlSi2O6·H2O) pollucite (CsAlSi2O6·nH2O). Saline slag ground, sieved (1 mm), washed separated into different sizes, larger an...
