本标准规定了测定土壤和沉积物中醛、酮类化合物的高效液相色谱法。
本标准适用于土壤和沉积物中甲醛、乙醛、丙烯醛、丙酮、丙醛、丁烯醛、丁醛、苯甲醛、异戊醛、正戊醛、邻-甲基苯甲醛、间-甲基苯甲醛、对-甲基苯甲醛、正己醛、2,5-二甲基苯甲醛等15种醛、酮类化合物的测定。

Scope

This standard specifies a high-performance liquid chromatography method for the determination of aldehydes and ketones in soil and sediments. This standard applies to formaldehyde, acetaldehyde, acrolein, acetone, propionaldehyde, crotonaldehyde, butyraldehyde, benzaldehyde, isovaleraldehyde, n-valeraldehyde, o-methylbenzaldehyde, m-formaldehyde in soil and sediments Determination of 15 aldehyde and ketone compounds including methylbenzaldehyde, p-methylbenzaldehyde, n-hexanal, and 2,5-dimethylbenzaldehyde. When the sampling volume is 10 g and the constant volume is 10 ml, the method detection limit of 15 aldehyde and ketone compounds is 0.02-0.06 mg/kg, and the lower determination limit is 0.08-0.24 mg/kg. See Appendix A for details. 2
