Simultaneous determination of zinc(II), manganese(II) and iron(II) in pharmaceutical preparations.
The applicability of derivative spectrophotometry for simultaneous determination of zinc(II), manganese(II) and iron(II) in the form of PAR complexes was presented and discussed. Beer's law was obeyed in range 0.025-13 ppm for zinc 1-20, for manganese and 0.025-0.2 for iron ion. The elaborated method was applied successfully for determination of mentioned ions in pharmaceutical preparation without previous separation. The error of the determination did not exceed +/-3%.
