Determination of Trace Tellurium in Steel by Hydride Generation-ICP-AES
WANG Xiangyang
Abstract：A method for the determination of trace tellurium in steel by hydride generation-inductively coupled plasma atomic emission spectrometry was studied. The optimization experiment of hydride generation condition of tellurium was discussed. The optimization experiment of hydride generation of tellurium was discussed. The optimal determination condition of the sample is hydrochloric acid medium (40 mL/100 mL). The optimal working conditions of the instrument are as follows: RF power 1 350 W, atomizing air pressure 0.17 MPa, auxiliary gas flow 4.2 × 10-4 m/s. Under optimal conditions, a linear relationship is appeared between the intensity of the system and the tellurium ion concentration, the linear range is 0-0.01 mg/mL, detecting limit is 0.003μg/mL, and the relative standard deviation is 1.05%.
