ABSTRACT
Objective:
To establish the method for determination of tantalum and tantalum pentoxide in the air of workplace by inductively coupled plasma optical emission spectrometry (ICP-OES).Methods:
The tantalum and tantalum pentoxide in the workplace air were collected by filter membrane and then digested by microwave digestion apparatus in the mixed solvents (HNO(3)â¶HF=3â¶1) ,diluted to 50 ml and detected by ICP- OES.Results:
The linearity of tantalum was good at the range of 0.0~100.0 µg/ml with a correlation coefficient of 0.9997, the LOD and LOQ were 0.04 µg/ml and 0.14 µg/ml, respectively. The recovery was ranged from 83.1%-87.8%; the RSD of intra-and inter-batch precision were 0.2%-1.0% and 1.1%-2.4%, respectively. The recovery was ranged from 87.4%-93.3%; the RSD of intra-and inter-batch precision were 0.5%-1.5% and 1.3%- 1.8%, respectively.Conclusion:
The determination method meet the requirement of analysis and apply to the determination of tantalum and tantalum pentoxide in the air of workplace.Palavras-chave
