A simple and convenient spectrophotometric procedure is described for the determination of ampicillin. The method is based on the formation of a yellow ternary complex with 1,10-phenanthroline and copper(II) in acetate buffer solution \((\mathrm{pH} \simeq 5.0)\) and measurement at \(446 \mathrm{~nm
