Simultaneous Determination Of Cr(Iii) And Cr(Vi) Using Differential Pulse Polarography And Application To Gerede River, Olcay Şendi̇l, Nabeel Mohammed, Güler Somer
Simultaneous Determination Of Cr(Iii) And Cr(Vi) Using Differential Pulse Polarography And Application To Gerede River, Olcay Şendi̇l, Nabeel Mohammed, Güler Somer
Turkish Journal of Chemistry
Determination of Cr(III) in the presence of Cr(VI) from one polarogram is not easy. No such procedure was found in the literature. In polarographic studies Cr(III) had a peak only in acidic medium, while Cr(VI) had either 1 or 2 peaks in both acidic and basic solutions. In solutions that contain these 2 ions, the peak obtained in acidic medium for Cr(III) will be the sum of both ions. Thus, Cr(III) cannot be determined directly from one polarogram. In this work, a new and simple polarographic method is established for the determination of Cr(III) and Cr(VI) by using only one …
