Ke. Grant et al., QUALITATIVE DETERMINATION OF LOW-MOLECULAR-WEIGHT ORGANIC-ACIDS IN MIXED HAZARDOUS WASTES USING THERMOSPRAY LIQUID-CHROMATOGRAPHY MASS-SPECTROMETRY, Journal of radioanalytical and nuclear chemistry, 207(2), 1996, pp. 247-261
A technique has been developed for the qualitative determination of lo
w-molecular-weight organic acids in radioactive, mixed hazardous waste
s using thermospray liquid chromatography/mass spectrometry. A tank wa
ste was analyzed, and the results indicated the presence of citric, gl
ycolic, acetic, and nitrosoiminodiacetic acid (NIDA). Further investig
ation revealed NIDA was formed under acidic conditions with die reacti
on of iminodiacetic acid and the high nitrate/nitrite concentration pr
esent in the waste.
