Adsorption of Lead from Aqueous Solution by Modified Beech Sawdust
Sawdust is now being investigated as an adsorbent to remove contaminants from aqueous solution. Heavy metals can be decreased very effectively with the organic material. In this research, adsorption of Pb (II) onto modified beech sawdust in a batch system was investigated. Sawdust was collected from timber mill of Qom, Iran, and modified with H2SO4 and NaOH. Then, the effe...
متن کاملRemoval of Cr(VI) Species from Aqueous Solution by Different Nanoporous Materials
Background: The removal of toxic metals from sewage and wastewaters is one of the most important concerns in the twenty first century. The removal of poisonous Cr(VI) from aqueous solution by different low-cost available nanoporous adsorbents was investigated in the present study. Methods: Fumed silica, bentonite (BN), hydrotalcite (HT), MCM-41, Na-Y, mordenite (MOR) and SAPO-34 were ...
متن کاملApplication of ordered nanoporous silica for removal of uranium ions from aqueous solutions.
Ordered nanoporous silica (MSU-H) with high surface area has been utilized as a solid substrate of a surface-modified hybrid sorbent for the application to the removal of U(VI). Carboxymethylated polyethyleneimine (CMPEI) with a strong complexing property has been introduced to the pore surface of MSU-H substrate. CMPEI-modified MSU-H (CMPEI/MSU-H) has been characterized by scanning electron mi...
متن کاملAdsorption of Radioactive Materials by Green Microalgae Dunaliella Salina from Aqueous Solution
Introduction: Nuclear accidents release large quantities of radioactive materials into the environment. Iodine-131 and cesium-137 are two radionuclides released during nuclear accident, which can pose the greatest cancer risks. These radionuclides can be moved to other areas through rain and wind. The aim of this study was to develop efficient and economical biological...
