Per- and polyfluoroalkyl substances (PFAS) are a group of contaminants of great concern due to their toxicity and ubiquity in the environment. Remediation efforts historically have focused on granular activated carbon (GAC) because of its low maintenance and relatively low cost. However, GAC is not PFAS selective and is especially...
The 105,000 x g supernatant fluid (S[subscript HS]) from extracts of pea seedlings
(Pisum sativum, var. Alaska) etiolated for 60 hours yielded a
very potent adenosine triphosphatase activity. This activity was designated
as an apyrase when the reaction stoichiometry indicated that
adenosine triphosphate (ATP) was hydrolyzed to adenosine monophosphate
(AMP)...
The oxidation of triethylamine by the two electron oxidant
thallium(III) chloride was studied and the results compared to those
when triethylamine is oxidized by copper(II) halides. This study
requires anhydrous conditions since in an aqueous system thallium(III)
chloride is extensively hydrolyzed and triethylamine causes
precipitation of thallium(III) oxide. Most of...
The electrochemistry of cadmium at a Reticulated Vitreous
Carbon (RVC) electrode has been studied to determine the suitability of
RVC as a working electrode for the electrochemical preconcentration of
cadmium in the corrosive environment of zirconium dissolved in
hydrofluoric acid.
The electrochemistry in this investigation deals with deposition
of solid...
