The copper(I)-NC chelate does not absorb at 596 nm and consequently copper does not interfere with the determination of iron. The iron(II)-TPTZ chelate exhibits an absorbance at 458 nm that is 0.123 times its absorbance at 596 nm; therefore, correction for the effect of iron on the determination of copper is straightforward.
