| Abstract: | The trace stannum has been determined in zinc alloy by spectrophotometer by use of the stable violet red chelate formed with alizarin violet and stannum under the conditions of acidity 0.15N,wavelength 570nm and eliminating the interfering elements. The method is accurate and reliable by comparison experiment. |
