Zeolitic adsorbents have been developed for molybdenum recovery from various sources. The batchwise adsorption ability of molybdenum ion (Mo) with zeolite A type adsorbent could be improved when the counter cation (Na) was exchanged by divalent ions (Sr and Ca), while no significant difference was observed in the case of zeolite X type adsorbent. The adsorption ability for Mo was therefore base...

conclusions most patients are referred for restaging and demonstrate evidence of regional or distant metastasis with significant value for further treatment planning. providing insurance coverage and familiarizing referring physicians about appropriate indications of this relatively new diagnostic modality will be to the best interest of head and neck cancer patients in long term. methods we re...

re-vegetation of bare soil is believed to increase, or at least maintain the organic matter levels of soil. the aim of this study was to investigate the soil characteristics changes, nutrient pool sizes and their availability under mid canopy, and canopy gap positions of saltbush in an area re-vegetated with atriplex lentiformis. some of the physical and chemical soil characteristics (the parti...

The most studied catalysts for methane dehydroaromatization (MDA)?Mo/ZSM-5?are not commercialized yet due to the rapid deactivation and insufficient activity. Catalytic systems based on Fe Re are potential alternatives Mo-containing zeolites. Here, we compare catalytic performance of these as a function metal type its loading in ZSM-5 zeolite. results show that activity decreases order Re/ZSM-5...

This is a report on the extraction of molybdenum(VI) ions using a supported liquid membrane, prepared by dissolving in kerosene, the extractant Alamine 336 (a long-chain tertiary amine) employed as mobile carrier. A flat hydrophobic microporous membrane was utilised as solid support. Appropriate conditions for Mo(VI) extraction through the liquid membrane were obtained from the results of liqui...
