POLYMERIC FLUIDS FOR IN SITU REMEDIATION OF HEXAVALENT CHROMIUM USING TRAP AND TREAT TECHNOLOGY
Siwik, A., Master's Thesis, University of Guelph, 62 pp, 2019

In this study, natural polymers (scleroglucan, xanthan, guar, and carboxymethyl cellulose) were combined with the reducing agent sodium thiosulfate to create a gel to trap and treat Cr(VI). Batch tests, shear rheology, mechanical compression tests, microfluidic tests, and and other experiments showed that the proposed remediation technology was effective at simultaneously immobilizing and reducing Cr(VI), both with and without the presence of humic acids. https://atrium.lib.uoguelph.ca/xmlui/bitstream/handle/10214/15926/siwik_amanda_201904_Msc.pdf?sequence=1&isAllowed=y
