humic acid

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

殖对胺菊酯光敏作用显著，并随殖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，在利用风生产含植钾肥时，应根据作物类型选择工艺路线。

The new methods mainly contain the adsorption of natural materials, modification materials, humic acids, biosorption, quod of silicon micro encapsulization and nanotechnology.

主包括天然材料、改性材料的吸附,生物吸附,硅微囊技术和纳米技术等。

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根和植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.

摘植是一种有良好生物活性的有机高分子物质，风含有丰富的植。

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

以风褐为原料制备植(HA),将HA与普通型保水剂(PSA)复合,获得HA型保水剂(HA-PSA)。
