[Determination of calcium in calcium citrate and calcium malate by X-ray fluorescence spectrum].
Sample was pressed into a thin piece by a press machine. Sequential single channel X-ray fluoresence spectrum was used to determine the calcium content in calcium citrate and calcium malate. The whole process of sample preperation and determination takes only 10 minutes. In the present paper the determination of the calcium content in calcium citrate and calcium malate was studied. The result was compared with that of FAAS. The characteristics of the two methods were described respectively.
