前言 在一九六二年第三季度,我室收到某地区的一批沉积岩试样,他们除要求作光谱半定量全分析外,尚需对其中五个特定元素(锰、钒、铬、钴、镍)作光谱定量分析。上述五个元素由于含量很低(在万分之几到百万分之几),用一般的化学分析来作测定,具有费时、高成本之弊,且对某些元素而言,其分析灵敏度也不易达到要求。为此,须用光谱法来完成上述任务。
Foreword In the third quarter of 1962, a series of sedimentary rock samples from a certain area were received by our chamber. In addition to the requirements for semi-quantitative full-spectrum analysis, five specific elements (manganese, vanadium, chromium, Cobalt, nickel) for spectral quantitative analysis. Due to the low content of the five elements (a few parts to a few millionths), with the general chemical analysis for the determination, with the time-consuming, high-cost disadvantages, and for some elements, the analytical sensitivity Difficult to meet the requirements. For this purpose, spectroscopy is required to accomplish the above tasks.
