Application Summary AI generated
This standard specifies a method for determining lead and cadmium content in soil using potassium iodide-methyl isobutyl ketone (KI-MIBK) extraction combined with flame atomic absorption spectrophotometry. It is applied in environmental monitoring and soil quality assessment, particularly for analyzing heavy metal contamination in agricultural, industrial, or contaminated site soils. The method is used to achieve higher sensitivity and selectivity by extracting lead and cadmium into an organic phase before measurement.
