TL;DR: In this paper, hydrogen, sulfate, and dithionate are photocatalitically produced in good yield from aqueous solutions of sulfite by using platinum loaded cadmium sulfide powder.
Abstract: Hydrogen, sulfate, and dithionate are photocatalitically produced in good yield from aqueous solutions of sulfite by using platinum loaded cadmium sulfide powder as reported previously. The reaction rate has been greatly enhanced by the heat treatment of the catalyst, the refined method of platinum loading, the choice of pH of the solution, and temperature. Further details of the experimental conditins of the photocatalytic reactions have been pursued, and reported in this paper.
TL;DR: In the absence of oxygen, the major products were dithionate and sulfate with a molar ratio of 0.5 {plus minus} 0.08 as discussed by the authors.
Abstract: Aqueous solutions of sodium sulfite, with or without additives, were exposed to 254-nm radiation, and the yields of products were determined. In the absence of oxygen the major products were dithionate and sulfate with a molar ratio of 0.5 {plus minus} 0.08. From their total yield the quantum yield for the primay products, SO{sub 3}{sup {minus}} and e{sub aq}{sup {minus}}, was determined as 0.85 {plus minus} 0.04. In the presence of oxygen, dithionate was not observed and the formation of sulfate was extremely rapid, occurring with a quantum yield of about 500.
TL;DR: The reaction of nitrogen dioxide with aqueous sulfite solutions, in the presence and in the absence of oxygen, has been studied using Raman spectroscopy to determine product concentrations.
Abstract: The reaction of nitrogen dioxide with aqueous sulfite solutions, in the presence and in the absence of oxygen, has been studied using Raman spectroscopy to determine product concentrations. The products observed include nitrite, sulfate, and dithionate ions. The reaction appears to initially produce nitrite ion and sulfite radical: NO 2 +SO 3 2- →NO 2 - +SO 3 .- . The sulfite radical can undergo either recombination or reaction with oxygen to form SO 5 .-
TL;DR: BrO3- reduction was improved by increasing pH when pH is within 6.0-9.0, and principal component analysis demonstrated that pH is the most influential factor over sulfur(IV) concentration and type of UV lamp.
