本文报导用气相色谱法测定 NPK 复合肥料中的游离水。用经分子水处理过的无水乙醇作为复肥中游离水的提取剂,以 GDX-401为固定相,使用池检测器,外标法定量。此法的测水范围是0.2%～1.0%。
This article reports the determination of free water in NPK compound fertilizers by gas chromatography. With molecular water-treated anhydrous ethanol as compound fertilizer in the free water extract to GDX-401 as the stationary phase, the use of pool detector, external standard method. The method of measuring the water range is 0.2% to 1.0%.
