INFLUENCE OF pH ON THE OXYGEN ABSORPTION KINETICS IN ALKALINE SODIUM DITHIONITE SOLUTIONS
-Results from experimental studies on the influence of pH within the alkaline range on sodium dithionite oxidation with molecular oxygen reveal that it is possible to follow the kinetics of the process by observation of the consumption of base needed to maintain a constant pH. Under the conditions studied (partial oxygen pressure higher than 20,260 N/m z, pH > 8, 295 K ~ T ~< 318 K, and a dithi...
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 کاملMass Transfer Modeling of CO2 Absorption into Blended MDEA-MEA Solution
In this research, the thermodynamics and mass transfer of CO2 absorption has been studied in a mixture of MDEA-MEA amines. A relation is presented for mass transfer flux in the reactive-absorption process. For this purpose, the effective parameters on the mass transfer flux were investigated in both liquid and gas phases. Then, using dimensional analysis with the Pi-Buckingham theorem, the effe...
متن کاملRecovery 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...
