摘要:

The InF bands excited in a hollow cathode discharge have been used for fluorine determination in solid samples (containing from 10−6to 10−1% F) and solutions (at the F−concentrations from 1 μg/ml to 1 mg/ml). The discharge operated at direct current (dc) or high frequency current (hf). A dependence of the InF band intensities on the fluorine concentration has been investigated. Matrix effects caused by some metals and halides have been studied and discussed.
