Aqueous Cadmium Ions Removal by Adsorption on APTMS Grafted Mesoporous Silica MCM-41 in Batch and Fixed Bed Column Processes
Highly ordered mesoporous MCM-41silica with hexagonal structure was synthesized using extracted amorphous silica from sedge (Carex riparia) ash. Obtained mesoporous materials functionalized by 3-(Aminopropyl) trimethoxysilane (APTMS) and their structures characterized by means of X-ray diffraction (XRD), nitrogen adsorption-desorption, thermogravimetric analysis (TGA) and Fourier transform infr...
متن کاملRemoval of Lead from Aqueous Solutions by Polyacrylic Acid-Bentonite Composite: Batch and Column Studies
Shortage of water resources and deterioration of water quality have urged the need to develop new technologies for the removal of contaminants from water. Heavy metals produced by municipal and industrial activities are among the most toxic contaminants present in the natural and waste waters. Different methods have been developed for the elimination of heavy metals from water resources and ind...
متن کاملRemoval of Radioactive Cesium Using Prussian Blue Magnetic Nanoparticles
Radioactive cesium (137Cs) has inevitably become a human concern due to exposure from nuclear power plants and nuclear accident releases. Many efforts have been focused on removing cesium and the remediation of the contaminated environment. In this study, we elucidated the ability of Prussian blue-coated magnetic nanoparticles to eliminate cesium from radioactive contaminated waste. Thus, the o...
متن کاملKinetics studies of uranium sorption by powdered corn cob in batch and fixed bed system
Sorption of uranium (VI) from aqueous solution onto powdered corn cob has been carried out using batch and fixed-bed technique. The experimental results in batch technique were fitted well with pseudo second-order kinetics model. In the fixed bed technique, Thomas and Bohart-Adams models were evaluated by linear regression analysis for U(VI) uptake in different flow rates, bed heights and initi...
متن کاملBatch Removal of Acid Blue 292dye by Biosorption onto Lemna minor: Equilibrium and Kinetic Studies
Background; Recently, there has been a great concern about the consumption of dyes because of their toxicity, mutagenicity, carcinogenicity, and persistence in the aquatic environment. Therefore, the aim of this study was to determine the feasibility of using Lemna minor for Acid Blue 292 (AB292) dye removal from aqueous solution and to determine the optimal conditions. Methods; This experimen...
