Simultaneous determination of Cu(II) and Pd(II) as 4-phenylpiperazinecarbodithioate complex using H-point standard addition method and derivative spectrophotometry

A new, simple, inexpensive, and sensitive method for the simultaneous spectrophotometric determination of Cu(II) and Pd(II) by H-point standard addition method and derivative spectrophotometry is described. 4- Phenylpiperazinecarbodithioate (PPDTC) in an anionic micellar solution of SLS was used as a reagent at pH 4. The experimental parameters, such as pH, type of surfactant, concentration of reagent, and surfactant used, were optimized to minimize the errors. The linear ranges of the method were 0.1-10 and 0.1-11 m g mL-1 for Cu(II) and Pd(II), respectively. The results of applying H-point standard addition and fourth derivative spectrophotometry showed that Cu(II) and Pd(II) can be determined simultaneously with detection limits of 0.12 and 0.11 m g mL-1 respectively. Therefore, the method of H-point standard addition and fourth derivative spectrophotometry was used for resolving overlapped spectra for the determination of Cu(II) and Pd(II). This method was successfully applied to the determination of these metals in synthetic and real samples.
