【摘要】 传统制备腐植酸的方法是煤经过碱抽提,酸析出后得到腐植酸产品。本实验以酸活化理论为指导,使煤酸活化后将不溶性的腐植酸盐转换成腐植酸,再用碱抽提的方法制备腐植酸。和传统方法相比,酸活化法具有操作简单、资源利用率高、能耗低、产率高的优点。更多还原

【Abstract】 The humic acid is traditionally obtained by adding acid to the extracting liquid through base.Under the guidance of active acid theory,the humic xalt is changed into solved humic acid by active acid.Then the humic acid can be prepared by base extracting.Compared with classical approach,acid active preparation has many merits such as high product and resource using rate,low energy consuming and easy manipulating.更多还原
