Reversed-Phase Liquid Chromatographic Separation and Determination of Ni(II), Cu(II), Pd(II), and Ag(I) Using 2-Pyrrolecarboxaldehyde-4-phenylsemicarbazone as a Complexing Reagent

<table>The effect of variation of pH on the formation of  Pd(II), Ag(I), Ni(II), and Cu(II) as complexes of PPS against reagent blank. The final concentrations were 2, 1, 1, and 1 <i>μ</i>g/mL, respectively.</table>
