A new method has been proposed based on hollow fiber-based liquid three-phase micro
extraction and in-situ differential pulse anodic stripping voltammetry (DPASV) for the micro
extraction and quantification of mercury (II) ions. Different factors affecting the liquid-three
phases micro extraction, including organic solvent, pH of the donor and acceptor phases,
concentration of the complexing agent, extraction time, and stirring rate were investigated
and the optimal extraction conditions were established. Three microelectrodes designed ...
