The research discussed the possibility of adsorption Brilliant Blue Dye (BBD) from wastewater using 13X zeolite adsorbent, which is considered a byproduct production process potassium carbonate Iraqi potash raw materials. adsorbent was prepared and characterized by X-ray diffraction that showed clear match with standard zeolite. crystallinity rate 82.15% crystal size 5.29 nm. surface area pore ...

This research evaluated the importance of the adsorption properties of chitosan a chitosan/zeolite conjugate film for the removal of Cr(VI) ions from solutions in the 5-260 mg/L concentration range, when the pH was adjusted to 4.0 and 6.0. The uptake capacities of the films formed by chitosan and by the chitosan/zeolite conjugate were calculated by mass balance. The equilibrium isotherms were f...

slurries of rice-straw cellulose (obtained by delignification and removal of hemicelluloses from the powdered raw material) were subjected to ultrasonic waves at different intensities for various times (constant temperature). susceptibility of the samples to cellulose-hydrolysis increased initially with pretreatment time, reaching a maximum or a constant level thereafter. maximum glucose yield ...

Pressure swing adsorption (PSA) technology is used in medical oxygen concentrators for selective of nitrogen under pressure from air to produce oxygen-enriched breathing. The functional material aluminosilicate zeolite like Li-13X, 5A (LTA) with a relatively high Al-content. It selectively adsorbs the into their molecular sieves due strong quadrupolar interaction between adsorbed and electrical...
