The research presented by the authors in this paper focused on understanding behavior of mercury during coal combustion and flue gas purification operations. goal was to determine temperature emissions limits for lignites energy sector. examined process sorption from gases using fine-grained organic materials. main objectives study were recommend a low-cost adsorbent such as coke dust (CD), cor...
Fluoride is a poison that accumulates in our bones. It has been associated with cancer in young males; osteoporosis; reduced I.Q; and hip fractures in the elderly, to name a few. The permissible limit of fluoride concentration in drinking water is 1.5mg/L according to WHO guidelines. Therefore, knowledge of its removal, using best technique with maximum efficiency is needed. Among various techn...
Background and purpose: The presence of phenol and its derivatives in water and wastewater are of major concern because of their toxicity and threat to human life and environment. The aim of this study was determination of the modified lemna minor and azolla in phenol adsorption. Materials and methods: In this emperical-lab study, the washed lemna minor and azolla was used as adsorbents. The e...
Polyacrylate (PAA) adsorbents selectively bind low density lipoproteins (LDL) from human plasma and blood, whereas very low density lipoproteins (VLDL) are only minimally adsorbed. The adsorption of cholesterol-rich lipoproteins to PAA adsorbents is related to the molecular weight (mw) of the polyanion ligand. Ca(++) and Mg(++) inhibit the binding of LDL to PAA adsorbents. The chemical composit...
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
