in this study, degradation of p-chlorophenol (p-cp) was evaluated using persulfate (ps) activated zerovalent iron (zvi) based ultraviolet (uv) in a bench scale photoreactor. the effect of operational parameters such as solution ph (3, 7, and 11), reaction time (0-60 minutes), zvi dosage (0.15, 1.25, 0.5, 1, and 1.5 mm), ps concentration (0.5, 1.5, 2, 2.5, 3, and 4 mm), and initial p-cp concentr...

Ion chambers (ICs) are often employed to measure the concentration of tritium within flowing gases. In real-world environments, active surfaces ICs become covered with tritiated surface contaminants. This contamination creates a large background response that can mask signs interest, which is in gas phase. Previous efforts reduce effects utilize inert coatings (e.g., gold) and low area electrod...
