This review covers capillary electrophoresis (CE) methods for mercury speciation, detailing sample prep, separation, and detection. Advanced hyphenated techniques offer enhanced sensitivity and selectivity for accurate mercury analysis.

Area of Science:

  • Analytical Chemistry
  • Environmental Chemistry

Background:

  • Mercury speciation is crucial for understanding its environmental fate and toxicity.
  • Capillary electrophoresis (CE) offers a powerful platform for separating complex mixtures.

Purpose of the Study:

  • To review capillary electrophoresis (CE) methods for the speciation of inorganic and organomercury compounds.
  • To discuss sample preparation, separation conditions, and detection modes for mercury speciation using CE.

Main Methods:

  • Review of CE techniques, including complexation strategies (thiols, chelating agents) and non-complexation methods.
  • Discussion of detection methods: UV-visible absorption, hyphenated techniques (CE/ICP-MS, CE/AAS), and electrochemical detection.

Main Results:
