in this study, the adsorption of thallium (iii) ion from aqueous solutions onto modified znonanopowder as a fairly low cost adsorbent has been investigated in batch mode. it was found thatmodification of the adsorbent was essential for obtaining the significant adsorption percentage. theadsorbent modified by sodium phosphate solution. the effect of experimental parameters such asinitial ph of s...
Introduction: Increasing environmental pollution by the discharge of wastewaters containing copper has caused much concern because of the serious health effects, particularly the brain and liver and its bioaccumulation. The objectives of this study was to investigate the performance of a low-cost and natural adsorbent namely Falcaria vulgaris to remove Cu(II) ions from aqueous solution. Meth...
Cadmium can be found in wastewater in high concentrations and can cause dangerous effect on aqueous environment and human health. At present, many methods have been used to heavy metals removal. Among this clean up techniques, adsorption techniques by using low-cost adsorbent are more considerable. In this study, batch adsorption experiments were conducted for removal of cadmium ions from a...
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...
Classical xerogels are robust, inexpensive and nontoxic materials with low-ordered nanoporous structures. In water streams where the pH is higher than the Point of Zero Charge, the surface of classical xerogels such as tetraethoxy orthosilan (TEOS) xerogel is negatively charged. It was assumed that a xerogel can work as a strong adsorbent for metal ions without further modification. Therefore, ...
