摘　　要：为了建立快速鉴别海水与淡水珍珠的方法,采用X荧光光谱仪对海水和淡水珍珠粉进行元素检测,计算其锶钙计数比。结果表明,海水珍珠粉的锶钙计数比在0.2以上,淡水珍珠粉的锶钙计数比在0.2以下。因此依据这种锶钙计数比的明显差异,可以快速、无损地鉴别海水和淡水珍珠粉。To set up a rapid identification method for identifying seawater pearl powder and freshwater pearl powder,examined the elements of pearl powder by X-ray fluorescence spectrometer(XRF),and calculated the Sr/Ca ratio.Results showed that the Sr/Ca ratio of seawater pearl powder is above 0.2,freshwater pearl powder is below 0.2.Seawater pearl powder and freshwater pearl powder can be identified nondestructively and rapidly based on the obvious difference in their Sr/Ca ratio.
