超声波在空气中处理褐煤而制得的腐植酸的组成及结构,与用传统方法制得的腐植酸相比较,其特点是O/C、H/C原子比较高及在缩聚的芳香态中碳较少、同时CH_2~-,C=O醌基增加。建议O/C原子比及酚羟基、醌基中氧的总含量(O_(OH)+C=O醌基)占O~(d_af)的百分数作为评价所研究的腐植酸制剂生理活性的参数。 原料的预处理影响腐植酸的产率、组成及性质(天然材料的煤化程度、化学制剂的类
The composition and structure of humic acid produced by ultrasonic treatment of lignite in the air are characterized by higher O / C and H / C atomic ratios and more carbon in the polycondensation aromatic state than the humic acid obtained by the conventional method Less, while CH_2 ~ -, C = O quinone group increased. Proposed O / C atomic ratio and the phenolic hydroxyl group, quinone oxygen content (O - (OH) + C = O quinone) as a percentage of O ~ (d_af) as a study of the humic acid preparation physiological activity parameters. Pretreatment of raw materials affects the yield, composition and properties of humic acid (degree of coalification of natural materials, chemical class
