Approximately the same amount of sodium dithionite was added to the reference cuvette.
The iron and titanium were reduced chemically via sodium dithionite from 0.41% to 0.25% and 2.2% to 2.00%, respectively.
For this purpose, 50 mL (volume of the column) of the anaerobic buffer and then 40 mL of the buffer containing sodium dithionite (5 mL, 100 mg [mL.sup.-1]) were passed through the column.
In the context of limited literature data on in vivo sickling of erythrocytes with sodium dithionite and thiomersal, we consider it necessary to perform further testing in order to gather the preliminary data for developing a therapeutical malaria vaccine which would target the erythrocyte stage of the parasite.
Treatment with sodium dithionite to reduce MetHb and oxyhemoglobin, filtration to remove particulates, or other methods of pretreatment aid in making postmortem samples more suitable for CO-oximetry (3, 4).
If they do contain heavy metal complexes, however, they are first subjected to batch treatment with sodium dithionite or polysulphide to break up the complex compounds.
Once it reached the groundwater, the sodium dithionite reacted with iron in the ground and spread out in a circle about 50 feet in diameter.
Myotome Hb spectra are shown for the sample equilibrated with air or under anoxic conditions produced by addition of sodium dithionite. The air-equilibrated notochord samples show absorbance maxima at 418nm, 546nm, and 582nm ([+ or -]1 nm); the nitrogen-equilibrated samples show absorbance maxima at 435 nm and 556 nm ([+ or -]1 nm).

The extract of 0.1 mL was incubated in a solution containing 0.4 mL of 0.1 M potassium phosphate buffer (pH 7.4), 0.1 mL of 15 mM sodium nitrite, 0.2 mL of 5 mM methyl viologen, 0.2 mL of 86.15 mM sodium dithionite in a 190 mM NaHCO3.
The total iron present was verified by the addition of sodium dithionite, an agent known to release iron from gluconate or dextran complexes (5).
