本文通过对黄腐酸稀溶液吸光度影响因素的考察,探讨了黄腐酸在其稀水溶液中的存在状态,得出了黄腐酸在其稀水溶液中以胶体状态存在的结论。并对黄腐酸在不同pH值区间的胶体状态进行了讨论。
In this paper, by investigating the influencing factors of absorbance of fulvic acid dilute solution, the existence state of fulvic acid in dilute aqueous solution was discussed, and the conclusion that fulvic acid existed in colloid state in dilute aqueous solution was obtained. The colloidal state of fulvic acid in different pH range was discussed.
