humic acid

Humic acid had significant photosensitization on tetramethrin,and itsphotosensitization increased rapidly as the humic acid concentration increased.

酸对胺菊酯光敏化作用显著，并酸浓度的增加而迅速增强。

As a result, the method of using airslake-coal to produce potassium fertilizer including humic acid was varied with different crops.

因此，在利用风化煤生产含酸钾肥时，应根据作物类型择工艺路线。

Experiments show that causticizing by adding a small quantity of slaked lime can eliminate the interference of carbonate ions and humic acid salts.

添加少量的熟石灰可即刻消除碳酸根和酸盐等有机杂质的影响。

Humic acid is a kind of organic matter with high molecular quantity and satisfactory biological activity, and there are abundant humic acid in airslake-coal.

摘酸是一种有良好生物活性的有机高分子物质，风化煤中含有丰富的酸。

Humic acid (HA ) was abstracted from leonardite,and a composite superabsorbent (HA PSA ) was prepared by compounding poly (acrylic acid ) and lignitic humic acid.

以风化褐煤为原料制备酸(HA),将HA与普通型保水剂(PSA)复合,获得HA型保水剂(HA-PSA)。
