Qualitative and quantitative analysis of the light hydrocarbons produced by radiation degradation of N,N-diethylhydroxylamine

γ-ray damage of N,N-diethyl-hydroxylamine in water and its radiolytic products at lower dose

“…The analysis of H 2 was performed by gas chromatography in which 5 Å molsieve packed column and thermal conductivity detector (TCD) were equipped [17], carrier gas is Ar, and its flow is 10 mL min -1 ; column temperature is 85°C, TCD temperature is 110°C. The analysis of light hydrocarbon was also made by gas chromatography, but the column was PLOT Al 2 O 3 column, and the detector was FID [15], carrier gas is N 2 , and its flow is 30 mL min -1 ; column temperature is 65°C, FID temperature is 110°C.…”

“…The analysis of light hydrocarbon was also made by gas chromatography, but the column was Al 2 O 3 PLOT column, and the detector was FID [15], results show that there are methane, ethane, ethene, propane, propene and n-butane in the gas evolved from irradiated DEHA solutions. The response curves (volume range of standard gas mixture: 20.0-400.0 lL) and R 2 for hydrocarbon analysis are listed in Table 1.…”

“…Since the separation of Pu and Np from U is processed in radiation field, while organics are commonly sensitive to radiation, radiation damage of DEHA and its radiolytic products must be studied before its application. Reports [14][15][16][17] show that at higher dose to 1000 kGy, DEHA radiolytic rate is very high, and the relationships of radiolytic gas and organics quantity on dose and initial DEHA concentration are complicated. Another report [18] calculates that reagents used in the reprocess of spent fuel usually absorb about 10 kGy radiation energy, in order to give reliable reference to the application of DEHA in the reprocessing of spent fuel, we studied the radiolysis of DEHA at 5-25 kGy.…”
