Recovery of Cu(II) by chemical reduction using sodium dithionite.
Wastewaters containing Cu(II) along with ligands are ubiquitous in various industrial sectors. Efficacy of treatment processes for copper removal, especially precipitation, is greatly debilitated by ligands. Chemical reduction being commonly employed for production of metal nanoparticles has also been used for removing copper. Addition of ammonia was reported to be essential for improving coppe...
متن کاملThe reduction of diphosphopyridine nucleotide by sodium dithionite.
It is well known that diphosphopyridine nucleotide (DPN) can be reduced by sodium dithionite to give a product, DPNH, identical with that obtained by enzymic reduction. DPN can also be reduced by ionizing radiations under special conditions (Swallow, 1953), but theproductwas found to possess no coenzyme activity when tested with lactic dehydrogenase (Stein & Swallow, 1954). Barron, Johnson & Co...
متن کاملA Comparison of the Use of Sodium Metabisulfite and Sodium Dithionite for Removing Rust Stains from Paper
Presented at the Book and Paper Group Session, AIC’s 39th Annual Meeting, May 31–June 3, 2011, Philadelphia, Pennsylvania. shown, in the experiment presented in this paper, to have significant success in removing rust from paper. The intent of the experiment described in this paper was to compare both reducing agents’ ability to reduce and eliminate rust stains from paper. Qualitative results d...
متن کاملOxygen measurement via phosphorescence: reaction of sodium dithionite with dissolved oxygen.
A homemade instrument for the measurement of oxygen concentration in aqueous solutions measures the decay rate of the phosphorescence of a Pd-porphyrin complex (phosphor) dissolved in the solution, which is flashed every 0.1 s with 630 nm light. The concentration of O2 is a linear function of the decay rate. The instrument is used to study the reaction of dithionite (S2O42-) with O2 at 25 degre...
متن کاملSide reactions in the deoxygenation of dilute oxyhaemoglobin solutions by sodium dithionite.
Sodium dithionite (Na2S204) is the commonest and most convenient reagent for the deoxygenation and reduction of haem pigments. The danger of undesirable side reactions between haem pigments and Na2S204 or its oxidation products has been remarked by several workers (Hartridge & Roughton, 1923; Keilin, 1926, 1927; Zeile, 1932; Lemberg, Legge & Lockwood, 1941; Lemberg & Legge, 1949), and is partic...
