Removal of Fe2+ from Aqueous Solution Using Manganese Oxide Coated Zeolite and Iron Oxide Coated Zeolite
The adsorption of Fe2+ by the manganese oxide coated zeolite (MOCZ) and iron oxide coated zeolite (FOCZ) was studied. Surface properties of adsorbents have been investigated for monitoring their changes and morphology for both of the MOCZ and FOCZ. Main variables namely; contact time, pH, initial concentration of Fe2+, size and dosage of adsorbent have been optimized, and the results contrasted...
متن کاملReal-Time Manganese Phase Dynamics during Biological and Abiotic Manganese Oxide Reduction.
Manganese oxides are often highly reactive and easily reduced, both abiotically, by a variety of inorganic chemical species, and biologically during anaerobic respiration by microbes. To evaluate the reaction mechanisms of these different reduction routes and their potential lasting products, we measured the sequence progression of microbial manganese(IV) oxide reduction mediated by chemical sp...
متن کاملRemoval of Mn from aqueous solution by manganese oxide coated zeolite
The preparation, characterization, and adsorption properties of Mn by manganese oxide coated zeolite (MOCZ) and its ability in removing Mn by adsorption were investigated. Characterization analyses were used to monitor the surface properties (and their changes) of the coated layer and metal adsorption sites on the surface of MOCZ. The adsorption experiments were carried out as a function of sol...
متن کاملPolyaspartic acid coated manganese oxide nanoparticles for efficient liver MRI.
We report in this communication a simple, facile surface modification strategy to transfer hydrophobic manganese oxide nanoparticles (MONPs) into water by using polyaspartic acid (PASP). We systematically investigated the effect of the size of PASP-MONPs on MRI of normal liver and found that the particles with a core size of 10 nm exhibited greater enhancement than those with larger core sizes.
متن کاملNickel and lead sequestration in manganese oxide-coated montmorillonite.
Amorphous hydrous manganese oxide (HMO) is an important mineral in soils and sediments influencing the mobility and bioavailability of metal contaminants. In this study, nickel and lead sorption to discrete HMO and HMO-coated montmorillonite was investigated mechanistically. The effect of pH and concentration revealed that when normalized to the mass of oxide present, the HMO-coated montmorillo...
