全国岩矿分析经验交流会于4月30日至5月5日在广西桂林召开。这次会议有来自全国二十九个省市自治区的198个单位的248名代表和81名列席代表。向大会提交的论文达600多篇无论在数量上还是在质量上较过去都有很大提高。在电化学分析方面,极谱催化波有了新的发展。为稀土元素及铂族元素的催化极谱分析工作作得更加完美。离子择选电极除应用于地质样品中的氟、氯等元素外,已扩大大到银和钙元素。在原子吸收方面,不仅作岩矿中微量元素的分析,而且对于硅酸盐样品中高含量元素的分析也作了不少工作。氢化物一原子吸收法;无色散原子萤光法及氧屏蔽原子吸收法,新方法也都应用于地质试样分析。
National experience in exchange of rock and mine analysis will be April 30 to May 5 held in Guilin, Guangxi. There were 248 delegates from 198 units and 81 attending delegates from 29 provinces, autonomous regions and municipalities throughout the country. More than 600 papers submitted to the conference have greatly improved both in quantity and in quality. In electrochemical analysis, polarographic catalytic wave has been a new development. Catalytic polarographic analysis of rare earth elements and platinum group elements work more perfect. Ion selective electrode in addition to the geological samples of fluorine, chlorine and other elements, has been expanded to large silver and calcium. In terms of atomic absorption, not only for the analysis of trace elements in rock and mine, but also for silicate samples of high content of elements in the analysis also made a lot of work. Hydride-atomic absorption spectrometry; non-dispersive atomic fluorescence spectrometry and oxygen barrier atomic absorption method, the new method are also used in geological sample analysis.
