Determination of copper, iron, manganese, zinc, boron and molybdenum in fertilizers
Plasma emission spectrometry
1 Scope
This standard specifies the method of determination of copper, iron, manganese, zinc, boron, molybdenum content of fertilizer by plasma emission spectrometry (ICP).
This standard applies to copper, iron, manganese, zinc, boron, molybdenum content ≤ 1% of the fertilizer.
The detection limit of this standard method of copper 0.003μg/mL, iron 0.03μg/mL, manganese 0.004μg/mL, zinc 0.03μg/mL, boron
0.05 μg/mL, molybdenum 0.007 μg/mL.
