RISQuaternized Poly(4-Vinylpyridine) Coated Activated Carbon: Diffusion Controlled Sorption of Chromium(VI)
Publisher: American Society of Civil Engineers
Abstract: Quaternized poly(4-vinylpyridine) coated activated carbon has been proven to be successful in removal and recovery of
Adsorptive Removal of Parts per Million Level Selenate Using Iron-Coated GAC Adsorbents
Publisher: American Society of Civil Engineers
Abstract: Selenate removal by adsorption using iron-coated granular activated carbons (Fe-GACs) is reported in this study. Adsorption kinetics and equilibrium experiments with initial selenium concentration of 1 mg/L were conducted ...
Adsorptive Selenite Removal Using Iron-Coated GAC: Modeling Selenite Breakthrough with the Pore Surface Diffusion Model
Publisher: American Society of Civil Engineers
Abstract: Iron-coated granular activated carbon (Fe-GAC) was proven to be effective for removing selenite from aqueous solution in batch studies. Design and use of the adsorbent in column settings requires understanding the key mass ...
Chromium(VI) Removal by Modified PVP-Coated Silica Gel
Publisher: American Society of Civil Engineers
Abstract: This research involved the synthesizing of a reactive polymer, long alkyl quaternized poly(4-vinylpyridine) (PVP), and coating it onto the surface of silica gel to produce a granular sorbent to remove Cr(VI) from water. ...
Factors Affecting Chromium(VI) Removal by Modified Poly(4-Vinylpyridine) Coated Silica Gel
Publisher: American Society of Civil Engineers
Abstract: A reactive polymer, alkyl quaternized poly(4-vinylpyridine) (PVP) was synthesized and coated on the surface of silica gel to test its ability to remove Cr(VI) from water. Batch experiments were conducted with the coated ...
