摘要
采用红外光谱和拉曼光谱研究了企鹅珍珠贝天然珍珠的矿物组成;采用X荧光光谱仪对企鹅珍珠贝天然珍珠进行了元素检测,并计算锶/钙计数比率;采用钴^(60)-γ射线(装源100万Ci)对企鹅珍珠贝天然珍珠进行辐照处理3 h、6 h、9 h、12 h和15 h,观察其颜色的变化。结果表明:企鹅珍珠贝天然珍珠的矿物成分为文石;锶/钙计数比率在0.2以上;经过辐照处理,颜色没有变化。提出了开发利用企鹅珍珠贝天然珍珠的建议。
Infrared spectrum and Raman spectra analysis were used to study the mineral composition of natural pearl of Pteria penguin;X-ray fluorescence spectrometer(XRF)was used to examine elements of the natural pearl,calculated the ratio of Sr to Ca;irradiation treatments were set,in which natural pearl with ^(60)Co-γirradiation(1.00 million Ci radiation source)lasted 3 h,6 h,9 h,12 h and 15h to observed its changes of color.The results showed that the natural pearl are composed of aragonite;the ratio of Sr to Ca of natural pearl is more than 0.2;after irradiation treatments,color of the natural pearl does not change,based on which suggestions were put forward to develop and utilize natural pearl of P.penguin.
