Development of a method for the speciation of mercury in environmental sample analysis (Pembangunan kaedah bagi analisis penspesian merkuri dalam sampel analysis)

Trace concentrations of mercury in water samples were determined by a method involving a simple and rapid procedure connecting the flow-injection inductively coupled plasma mass spectrometry (FI-ICP-MS) and graphite furnace atomic absorption spectrometry (GFAAS) techniques. Mercury vapor, generated...
