Study on the Content of Zinc Oxide in Calamina Mineral Medicine and Pieces by Ultraviolet-visible Spectrophotometry
Objective : To establish the UV spectorphotometry for the determining zinc oxide content in crude drug and processed pieces of Calamina. Method: Chromogenic method of zinc reagent was used. The content of zinc oxide in 9 batches of crude drug and 13 batches of processed pieces were determined by UV spectorphotometry. Standard curve method was used in the calculation of the content. Result: The average recovery rate of sample was 99.72% with RSD 1.85%. Conclusion: This method is accurate
simple for the determination of zinc oxide. It is suitable for quality control of Calamina herbs and pieces.
