| 摘 要： | 利用甲醇-硫酸混合液(体积比10∶7)对土壤和白菜中低分子量有机酸同时进行提取和甲酯化衍生,然后利用二氯甲烷液-液萃取,气相色谱法分析。土壤中7种低分子量有机酸(草酸、丙二酸、反丁烯二酸、琥珀酸、马来酸、L-苹果酸、柠檬酸)的添加回收率为81.93%~95.58%,白菜中的添加回收率为84.78%~106.99%,方法的检出限为0.72~4.14 mg/kg。方法用于测定根际、非根际土壤和白菜根系、茎叶中的低分子量有机酸,结果准确可靠。

| Abstract: | The low molecular weight organic acids(LMWOAs) in rhizosphere soil,bulk soil,root and leave of cabbages were extracted and derived by the mixture of methanol and sulfuric acid(10∶7).Seven organic acids(oxalic,malonic,fumaric,succinic,maleic,L-malic and citric acid) were identified and quantified by GC instrument equipped with FID.The recovery were ranged from 81.93% to 95.58% for soils and from 84.78% to 106.99% for roots.The detection limit was ranged from 0.72 mg/kg to 4.14 mg/kg.The method was suitable for the reliable and accurate determination of low molecular weight organic acids in soils and cabbages. |
