Determination of mercury by electrochemical cold vapor generation atomic fluorescence spectrometry using polyaniline modified graphite electrode as cathode

Atomic spectrometry in China: past and present

“…228 To avoid contamination when using THB, an electrochemical hydride generation technique was proposed by Huang's group, 102,229 which is suitable for AES/AFS or ICPMS. Electrochemical cold vapor generation behavior was further explored using a modied cathode such as polymer modied graphite electrode 230 and L-cysteine modied graphite electrode. 231…”

Advances in atomic spectrometry and related techniques

“…Jiang et al 130 described an electrochemical cold vapour system with polyaniline modified graphite electrode as the cathode material coupled with AFS. The system with the polyaniline/ graphite electrode exhibited higher sensitivity, stability, and a lower Hg memory effect compared with a graphite electrode electrochemical system.…”

Determination of Trace Mercury in Cosmetics by Suspension- Sampling Hydride Generation Atomic Fluorescence Spectrometry

“…Development of precise techniques applied to the determination of Hg in traces contributes greatly to the knowledge of the presence of Hg and risk to the environment and human health. The most widely used techniques for Hg determination include gas-diffusion (GD) 2 , atomic emission spectrometry (AES) 3 , atomic absorption spectrometry (AAS) 4,5 , atomic fluorescence spectrometry (AFS) 6,7 , inductively coupled plasma mass spectrometry (ICP-MS) 8 and modified electrode (ME) 9 , that recently have been suggested for determination of very low concentrations of Hg in water and biologic material. Considerably, less investigated were materials like cosmetics, which play a very important role in the modern life and is easily contaminated by additional quantities of Hg.…”
