In this work, the removal of copper from an aqueous solution by granular activated carbon (GAC) in the presence of competitor ions was studied. A batch adsorption was carried out and different parameters such as pH, contact time, initial copper concentration and competitor ions concentration were changed to determine the optimum conditions for adsorption. The optimum pH required for maximum ads...

The article is aimed at increasing the probability of successful IT project completion by identifying sources 105 universal risks as well establishing cause-and-effect relationships between these risks. presents results an analysis relevant to projects; five them are commercial risks, 45 compliance and 55 Risk was carried out using 5Why, SWIFT Harrington coefficients. Based on analysis, root ca...
