Description
This powerpoint presentation begins by providing a brief overview of perchlorate and cationic surfactants. Hypotheses to test were: thiosulfate and other reduced sulfur speciescompetes with perchlorate for adsorption siteson the tailored granular activated carbon (GAC); proportional diffusivity is not the appropriatesimilitude equation for surfactant tailored GAC; and, loading of surfactant to GAC plays a role inperchlorate adsorption. Topics covered include: reduced sulfur species; thiosulfate oxidation rate; and, effect of anions on perchlorate adsorption to TGAC. Conclusions indicated that: Thiosulfate affects the adsorption of perchlorate toTailored GAC; proper prechlorination can markedly diminish theeffects of thiosulfate; anions such as nitrate interfere with the adsorptionof perchlorate to TGAC; and, oxidized forms of sulfur (SO<sub>4</sub><sup>2-</sup>) do not affect theadsorption of perchlorates as much as thiosulfate. Includes table, figures.
