3 PRINCIPLE OF THE METHOD
The sample was mixed with hydrochloric acid and nitric acid at room temperature to dissolve after inductively coupled plasma atomic emission spectrometer measured at a wavelength corresponding analysis
Lead, iron, copper, arsenic, selenium, bismuth, cadmium, mercury emission intensity, against a standard curve to determine the concentration of each element in the sample and calculate each element
content.
