Removal of chromium(VI) ions from synthetic solutions by the fungus Penicillium purpurogenum
(Wiley, 2004)The ability of Penicillium purpurogenum to bind high amounts of chromium(VI) from aqueous solutions is demonstrated. Cr(VI) adsorption capacity increases with time during the first four hours and then leveled off toward ... -
Removal of heavy metal ions by dithiocarbamate-anchored polymer/organosmectite composites
(Elsevier Science BV, 2006)In this study, the dithiocarbamate-anchored polymer/organosmectite composites were prepared for the removal of heavy metal ions (lead, cadmium and chromium) from aqueous media containing different amounts of these ions ... -
Removal of heavy metal ions from aquatic solutions by membrane chromatography
(Elsevier Science BV, 2000)Polyvinylalcohol membranes were prepared by a solvent casting technique. Metal-complexation ligand, i.e. monochlorotriazinyl-dye Cibacron Blue F3GA was then attached. These membranes with a high water content of 119%, and ... -
Removal of heavy metal ions using the fungus Penicillium canescens
(Multi Science Publ Co LTD, 2003)The potential use of the fungus Penicillium canescens for the removal of cadmium, lead, mercury and arsenic ions from aqueous solutions was evaluated in this study. Equilibrium biosorption of the heavy metal ions was ... -
Removal of lead (II) and nickel (II) ions from aqueous solution using activated carbon prepared from rapeseed oil cake by Na2CO3 activation
(Springer, 2015)In this study, rapeseed oil cake as a precursor was used to prepare activated carbons by chemical activation with sodium carbonate (Na2CO3) at 600 and 800 A degrees C. The activated carbon with the highest surface area of ... -
Removal of Lead (II) Ions from Aqueous Solutions onto Activated Carbon Derived from Waste Biomass
(Hindawi Publishing Corporation, 2013)The removal of lead (II) ions from aqueous solutions was carried out using an activated carbon prepared from a waste biomass. The effects of various parameters such as pH, contact time, initial concentration of lead (II) ... -
Removal of mercury species with dithiocarbamate-anchored polymer/organosmectite composites
(Elsevier Science BV, 2008)Mercury is one of the most toxic heavy metals found in solid and liquid waste disposed by chloro-alkali, paint, paper/pulp, battery, pharmaceutical, oil refinery and mining companies. Any form of mercury introduced to ... -
