3 Principle
After the specimen is digested with concentrated acid and the digested solution is diluted and scaled to the volume, emission intensity of lead and cadmium is determined with inductively coupled plasma emission spectrometer (ICP-AES) under appropriate conditions; by comparison of standard work curves, concentration of various metal ions is determined and total amount of heavy metal in the specimen is calculated.
