Abstract :

Zink is an important micronutrient that can be used to supplement the therapy of diarrhea in children. To ensure the quality and effectiveness of zinc syrup, zinc determination has been done based on the intensity of the color of zinc-dithizone complex in acetone: propanol (1: 1) using visible spectrophotometer. Zinc concentrations are compared with complexometry method using EBT indicator. The concentration of zinc in samples using complexometry method was (106.1 ± 0.02)% of the amount listed on the label. Result of the zinc assay by complexometry method is more accurate than the result that obtained using visible spectrophotometer method.
