一种黄壤的不同提取液的GC-MS有机成分分析
GC-MS Analysis of Organic Components of A Yellow Soid with Different Extracts
摘要
Abstract
In order to understand the organic composition, a yellow soil which developed from the Quarternary Period were extracted by different solvents (methanol: acetone= 1: 1, methanol: dichloromehan =1 : 1), the chemical components of the extracts were determined by GC-MS. Twenty seven components were identified from the methanol-acetone extracts, with a ratio of identification of 98. 3 ％, while 23 components were identified from methanol-dichloromethane extract, with a ratio of identification of 84.5 ％. It was concluded that the mixture of methanol-acetone was the optimal solvent to extract organic mater from the soil. The main component was acetic acid, accounting for 43.6 ％ of the identified components. However, the results of the two solvent systems were not the same, therefore, whether or not the presence of organic matter was the leading cause to soil acidification was not clear.关键词
