四川省德阳地区泥炭资源的表征及质量评估

CHEMICAL ANALYSIS FOR EIGHT SAPROPEL SAMPLES FROM SICHUAN DEYANG AND THEIR QUALITY EVALUATIONS

本文报导了对四川省德阳地区八种不同来源的泥炭进行全面分析的结果,并与黑龙江省腐值土及山西褐煤进行比较。结果表明,四川省德阳地区泥炭的腐植酸含量大都在20—30%之间,属于中腐酸泥炭,有机质含量在40—50%之间,属于中有机质炭。对从上述八种泥炭中提取的腐植酸进行表征,平均分子量为327.78,其结构是由C、N、H、O、S等元素组成,含有-COOH、-NH、-OH基的结构比较复杂的芳香有机化合物。

Chemical analysis has been carried out for eight sapropels from Sichuan province and compared with lignite from Shanxi province and humus soil from Heilongjiang province. The result shows that most of the eight Sichuan samples are of medium quality with respect to their content of humic acid which are about 20—30% and their content of organic constituents which are about 40—50%. The humic acid extracted from the above samples has been characterized by IR and ~1H—NMR. The average molecular weight for the Sichuan samples is 327. 78. Both of the IR and NMR results indicate that the humic acid is composed of C,N,H,O and S, and it's structure is akin to complicated aromatics containing—COOH,—NH and —OH functions.
