查询词典 oxidizing flame

The method has been used to determine Phthalic esters in drinking water and seawater sample. 3. Single drop microextraction, followed by gas chromatography with flame ionization detection has been applied to determine Formaldehyde, Acetaldehyde and Acraldehyde in water based on 2,4-Dinitrophenylhydrazine derivatization. Extraction solvent, extraction time and stirrer speed were optimized. Optimal experimental conditions were as follows: 1.6μL toluene microdrop exposed for 30 min in a 3ml aqueous sample placed in 4ml vial and stirred at 600 rpm/min.
