卡尔·费休法直接测定复合肥中的游离水

Determination of Free Water in Compound Fertilizers by Karl Fischer Method

直接把复合肥粉碎样加到卡尔·费休滴定容器中测定其游离水 ,省去萃取和离心步骤 ,既简化了操作 。

Compound fertilizers are pulverized and added directly into the Karl Fischer titration vessel to determine free water, thereby eliminating extraction and centrifuging, simplifying operation, and the reproducibility and accuracy of the analytical results are improved.
