Adsorption of Arsenate by Nano Scaled Activated Carbon Modified by Iron and Manganese Oxides
The presence of arsenic in water supplies is a major problem for public health and still concerns large parts of population in Southeast Asia, Latin America and Europe. Removal of arsenic is usually accomplished either by coagulation with iron salts or by adsorption with iron oxides or activated alumina. However, these materials, although very efficient for arsenic, normally do not remove other...
متن کاملAdsorption 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 کاملChromium Adsorption by Modified Wood
Chromium is one of the most common heavy metals which exist in very high concentrations in wastewater. The removal is very expensive due to the high cost of normal adsorbents. Lignocellulosic materials and mainly treated materials have proven to be a good solution for this problem. Adsorption tests were performed at different pH, different times and with varying concentrations. Results show tha...
متن کاملAdsorption Efficiency of Iron Modified Carbons for Removal of Pb(II) Ions from Aqueous Solution
Abstract Introduction: The Lead causes severe damage to several systems of the body, especially to bony tissues. Until now, several low-cost biosorbents have been studied for removal of heavy metal ions from aqueous solutions. In the present study, carbonized pomegranate peels modified with Fe2+ and Fe3+ ions and then it was investigated for removal of Pb(II) ions from aqueous solution. ...
متن کاملModified Process for High-Performance Anisotropic Sm2Fe17N3 Magnet Powder
The magnetic properties of an anisotropic Sm2Fe17N3 magnet powder were improved by enhancement of nitrogenation homogeneity. We made the Sm2Fe17 parent material powder by a reduction-diffusion method which contains a reduction-diffusion heat treatment and a subsequent wet process for removal of a CaO by-product. In the present study, as the modified process for the magnet powder, the nitrogenat...
