  • The first part of this thesis explores the synthetic method that converts carbon clad zirconia particles into chelation stationary phase. Oxine groups were attached onto the graphitic carbon surface by in situ generated diazonium ions in the aqueous solution. XPS, FTIR, SEM were utilized to characterize the functionalized particles, and optimum condition was investigated. The second part of this thesis applies the modified carbon clad zirconia particles into IC separation. The effects of various factors were studied. The last part of the work discussed the electrochemically modulated metal preconcentration. After grafting oxine groups on the glassy carbon surface, the binding of calcium can be controlled by the applied potential on the particle bed. Compared to the traditional preconcentration column, this technique can save the analysis time and simplify the equipment.
