ABSTRACT
Objective@#To establish the method for determination of barium sulfate in the air of workplace. @*Methods@#The barium sulfate was collected by dichloride ethylene filter membrane and then processed by alkali fusion method. Inductively coupled plasma optical emission spectrometry (ICP-OES) was used for the detection of barium sulfate. @*Results@#The sampling efficiency was 100%, the linearity of ICP-OES was good at the range of 0.1~100.0 μg/mL, the recovery was ranged from 93.0%~97.8%, the RSD of intra- and inter-batch precision were 3.7%~7.6% and 4.7%~8.8%, respectively. @*Conclusion@#The sampling method and determination method meet the requirements of analysis and apply to the collection and determination of barium sulfate in the air of workplace.
