摘　　要：以矿物源黄腐酸为原料,采用大孔型树脂(DAX-8)与离子交换树脂(001×7 H^+)进行提纯,使用灼烧法测定黄腐酸的含量。实验表明,使用DAX-8型树脂提纯黄腐酸的纯度为73.74%,使用001×7 H^+型树脂提纯黄腐酸的纯度为84.58%,DAX-8型树脂与001×7 H^+型树脂结合提纯黄腐酸的纯度为94.49%。001×7 H^+型树脂提纯黄腐酸的最佳工艺条件为:时间为120 min,温度为25℃,树脂用量为4 g。Using mineral fulvic acid as raw material,large pass resin(DAX-8)and ion exchange resin(001×7 H^+)were used for purification.The content of fulvic acid was determined by burning method.The results showed that the purification of fulvic acid were 73.74%and 84.58%by DAX-8 resin and 001×7 H^+resin,respectively.The purification result of combining DAX-8 resin and 001×7 H^+resin was 94.49%.The purification optimal process conditions of 001×7 H^+resin were 120 min,25℃,and 4 g resin dosage.
