What this standard covers

This standard specifies the determination of lead in soil, cadmium iodide - methyl isobutyl ketone (KI-MIBK) extraction and flame atomic absorption spectrophotometry. The detection limit of the standard (by weighing 0. 5g sample digestion volume to 50ml calculated) as: Lead 0. 2mg/kg, cadmium 0. 05mg/kg. When the test solution with higher levels of copper, zinc, consume potassium iodide, potassium iodide should be appropriate to increase the amount.
