Abstract Details

2012, Master of Science in Chemistry, Youngstown State University, Department of Chemistry.
Continuous flow hydride generation coupled with laser induced fluorescence spectrometry (HG-LIF) has been investigated for the measurements of Bi (III) and Ge (IV) in aqueous samples. The developed HG-LIF method has been evaluated in terms of analytical figures of merit. The limits of detection calculated are 0.03 ng/mL and 0.1 ng/mL for Bi and Ge, respectively. The accuracy of this method has been evaluated by analysis of a NIST standard reference material. The analytical utility of masking reagents has been investigated by performing recovery studies on a multielement ICP standard reference material. The HG-LIF approach has been applied to the measurements of Bi in a commercial medicine, and different kinds of tea leaves. The analytical utility of HG-LIF technique for measurements of Ge has been evaluated by analyzing a germanium supplement. The results of these studies demonstrated that HG-LIF approach has strong feasibility for Bi and Ge measurements in environmental samples.
