| Abstract: | The milk tablets were dissolved by HNO3-HClO4 mixed acid system, and the contents of calcium and magnesium in the samples were determined by inductively coupled plasma atomic emission spectrometry. The results revealed that the calcium and magnesium contents in the sugar-free milk tablets were relatively high. Through spiked recovery experiments, the recoveries of calcium and magnesium were between 96.72% and 101.40%, and the relative standard deviations were lower than 3%. The method is accurate and fast, which provides a foundation for studying the role of milk tablet in children"s growth and development. |
