There is a growing interest in the development of new methods for extraction of REEs from nuclear wastes.In this study, we fabricated a novel material composed of 1,10-phenanthroline-2,9-dicarboxilic acid (PDA)functionalized magnetic graphene oxide (Fe3O4/GO) for extraction of Sm(III) from aqueous solutions. Ourinterest in selection of carboxyl-containing ligand was due to its...
Arsenic is a highly toxic element for human beings, which is generally found in groundwater. Dissolved Arsenic in water can be seen as As+3 and As+5 states. The adsorption process is one of the available methods to remove Arsenic from aqueous solutions. Thus, this papers aims at removing Arsenic (III) from aqueous solutions through adsorption on iron oxide granules. The relation among four inde...
Chromium through natural processes and human activities enters the air, soil and water. Chromium-resistant bacteria are capable of reducing toxic Cr(VI) to less toxic Cr(III). In this work, batch studies were conducted to evaluate the effect of environmental factors on the rate of Cr(VI) reduction from synthetic wastewater of metal plating industry by Bacillus cereus under aerobic conditions. T...
[Ru(terpy)(bpy)(L)]PF6 complexes, where terpy is 2,2 ́:6′,2′′– terpyridine, bpy is 2,2 ́ bipyridine and L is monoanions of 4 bromophenylcyanamide (4 Brpcyd), 4methoxyphenylcyanamide (4 MeOPcyd), 2, 4 dibromophenylcyanamide (2,4 Br2pcyd), 2,4dimethylphenylcyanamide (2,4 Me2pcyd), 2 methylphenylcyanamide (2 MePcyd), phenylcyanamide (Pcyd) and naphtylcyanamide (ncyd) have been prepared and character...
Purpose: The purpose of this study is to compare the time-course changes in condylar long axis and skeletal stability after sagittal split ramus osteotomy (SSRO) with unsintered hydroxyapatite (u-HA) / poly-L-lactic acid (PLLA) plate, PLLA plate versus titanium plate. Patients and Methods: Of 60 Japanese patients diagnosed of mandibular prognathism, 20 underwent SSRO with u-HA/PLLA plate system...
