Theses and Dissertations

Guar gum (GG) is a promising product increasingly used in a variety of industries. It is nontoxic, inexpensive, and biodegradable. This research evaluated novel approaches using GG as an adsorbent for aromatic organic water contaminants. The application of GG demonstrated some effectiveness against all contaminants tested. Two brands of GG were tested using 5 different GG treatment strategies. Various experiments demonstrated nearly complete removal of Allura Red dye, Brilliant Blue dye, Erythrosine B dye, Methylene Blue dye, Tartrazine dye, and 2,4-dinitrotoluene; additionally, 78% adsorption was observed for Fast Green dye. GG typically removed less than 10% of toluene, which rapidly …
