Spectrophotometrie Determination of Zinc(Ⅱ) in Water with Dimethyl Phenol Orange

Gu Zhuming  
A spectrophotometric determination of trace amount of zinc in water. with dimethyl phenol orange as color developer is introduced, Some interference ions and the elimination of their influence on determination are discussed in detail. Ascorbic acid is. used to reduce ferric ions, ammonium fluoride to mask the interference of tin, Al, titanium, zirconium and rare earth elements, sodium thiosulfate to mask Cu and cadmium, and L-cysteine to mask Ni. As for Pb, no ideal masking agent is found at present. It is suggested to apply potassium ferrocyanide solution in order to make Zn(II)-XO complex copound distroyed and decolored, but with no effect on Pb(II)-XO. Take this solution as reference to determine the absorbance, the interference of Pb can he offset. Test shows that by this method the interference of ling Pb can be eliminated without any effects on Zn determination. It is a simple, convenient and rapid method, with high sensitivity and no need of extract operation.
