Abstract
A simple, rapid method is reported for the determination of vitamin C in effervescent tablets containing other vitamins and several trace el ements such as Mg(II), Zn(II), Fe(II), Mn(II), Cu(II) and Mo(VI). The procedure was developed on the basis of the bromate ion-iodide ion-asc orbic acid clock reaction (Landolt reaction). interference effects of air oxygen and metal ions and the role of pH are discussed in detail.
