摘要
研究了褐煤中腐植酸的交换容量;HNO3、H3PO4对腐植酸含量的影响;同时研究了褐煤腐植酸中杂质的固定与清除.
In this paper, the exchange capacity of humic acid extracted from brown coal was determined and the effects of nitride acid and phalate acid on the production of humic acid extracted from brown coal were studied. Meanwhile, the method of how to clear and fix theimpure components of humic acid was also studied.
