关于腐植酸与金属的配合作用的研究已有不少报导,但至今对腐植酸的结构还不清楚,一般认为它是兼有邻苯二甲酸和水杨酸型的大分子化合物。至于应用上如何选择各种腐植酸产物也无充分依据。我们用凝胶过滤法考察了黄腐酸分子大小对配合量
There have been many reports on the coordination between humic acid and metal. However, the structure of humic acid is still unclear so far. It is generally considered as a macromolecular compound containing both phthalic acid and salicylic acid. As for the application of how to choose a variety of humic acid products are not fully substantiated. We used gel filtration method to examine the amount of fulvic acid on the amount of compounding
