- W2380457592 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." @default.
