Determination of Thallium,Arsenic,Cadmium and the Other Harmful Elements in the Air of the Lead Smelting Workplace by Inductively Coupled Plasma Emission Spectroscopy
The rapid detection of thallium,arsenic,cadmium and the other harmful elements in the air of the lead smelting workplace is a problem,so the upgraded inductively coupled plasma emission spectroscopy is adopted,the microporous membrance is adopted to collect fume in the air,perchloric acid and nitric acid is adopted to dissolve sample,the standard solution of thallium,arsenic,cadmium is prepared,and ICP-AES instrument is used for selection and interference correction of thallium,arsenic,cadmium spectral line,therefore,one-time dissolution can be realized,at the same time,determination of harmful elements in several kinds of heavy metals can be finished,the method is fast and accurate,the addition standard recovery rate of experimental study is in the range of 98％～103％,the detection limit of thallium,arsenic,cadmium separately reach to 0.001 5 μg/mL,0.002 1 μg/mL,0.000 1 μg/mL,and so on,so the requirements for the rapid detection of harmful elements in the air can be meet.
