Kinetics, mass transfer, and mass re-equilibrium for arsenate adsorption on iron oxide-based carbons
(University of Missouri--Columbia, 2018)
MC was altered to another steady state by an in situ extraction with nano-FeAC in both batch and column systems. The overall inter-medium mass transfer resulted in both improved adsorption densities obtained by batch tests and a large bed volume prior to the 10...
Arsenic adsorption onto iron-chitosan composite from drinking water
(University of Missouri--Columbia, 2006)
ions on arsenic removal for CFeN was determined. For CFeN adsorbent, high removals of arsenate were obtained at pH range 5.8-7.8, with maximum removal occurring around pH 5.8. Arsenite removal is also efficient with the maximum removal occurring around...
Development and evaluation of innovative iron-containing porous carbon adsorbents for arsenic removal
(University of Missouri--Columbia, 2006)
for arsenic removal was evaluated by both batch and column studies. Effects of ionic strength, pH, and other competing constituents on the arsenic removal were also studied in batch systems. Redox transformation and surface characteristics of carbon based...
Organic-inorganic hybrid materials for arsenic adsorption : surface complexation and intraparticle diffusion
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Arsenic removal through adsorption is one of the most widely applied techniques for arsenic removal from drinking water. Among the numerous arsenic ...
Use of fluorescence excitation emission matrix spectroscopy for water and wastewater characterization
(University of Missouri--Columbia, 2006)
.Chemical compound samples prepared in the laboratory whereas water and wastewater samples were collected form around the state of Missouri and Kansas. Samples were filtered and properly diluted before they were scanned for EEMS. 3-D signatures of water...
Arsenic rejection by membrane processes : model development and application
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This study investigated the rejection of arsenic by several nanofiltration and inorganic clay membranes. Laboratory-scale experiments were conducted ...
Aquatic toxicity of one dimensional carbon nanomaterials
(University of Missouri--Columbia, 2010)
This study determined the toxicity of one dimensional carbon nanomaterials (CNMs) to amphipods, midge, oligochaetes and juvenile mussels in water and sediment. As-produced or modified carbon nanotubes (CNTs) and silicon ...
Fluorescence spectroscopy and parallel factor analysis of waters from municipal waste sources
(University of Missouri--Columbia, 2007)
Excitation-emission matrix (EEM) fluorescence spectroscopy is becoming a valuable tool for studying the complex nature of dissolved organic matter. EEMs can identify fluorescence emitting organic substances (fluorophores) ...
Plasma treatment effects on resin-based tooth restoration improvements
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The dental restoration is the recovery of the function, integrity and morphology of missing tooth structure using dental restorative materials. Recent ...
