Chemiluminescence vs. Kjeldahl determination of nitrogen in oil shale retort waters and organonitrogen compounds
The applicability of combustion/chemiluminescent nitrogen analysis to quantifying nitrogen in oil shale wastewaters and various representative chemical classes was demonstrated. Only azoxy compounds and those containing the pyrazole nucleus were not amenable to analysis. The majority of 56 compounds tested yielded from 90% to 110% of their theoretical nitrogen contents: enhanced recovery was found for nitrogen oxide salts. For 12 oil shale wastewaters, combustion/chemiluminescence gave total nitrogen values (1100-28800 mg/L) that did not differ statistically (P > 0.10) from those obtained by the time-consuming wet-chemical Kjeldahl method. The relative standard deviations for ten matrix or solvent effects were found. 28 references, 1 figure, 3 tables.
