硫化镍试金预富集-ICP-AES测定矿石中的Pt、Pd、Ir、Au

详细研究了硫化镍试金预富集－ICP－AES测定矿石中的Pt,Pd,Ir,Au的多种影响因素，结果表明硫化镍扣用盐酸溶解，多孔玻砂坩埚过滤溶液，盐酸和双氧水溶解残渣是比较理想的分析方案，硫化镍扣溶解过程中，Pt,Pd的损失可忽略。Au的损失相当高，仅能半定量，对于μg/g级的样品，Pt,Pd,Ir,Au的平均回收率在96－99％之间，相对标准偏差为1．7％－6．8％（n=5)，拟定的方法已用于矿石、精矿的分析。     

铂族元素和金的硫化镍试金预富集在现代仪器分析方法中的应用

评述了硫化镍试金预富集贵金属，然后采用中子活化法、感耦等离子体质谱法、原子吸收光谱法以及感耦等离子体原子谱法测定痕量、超痕量贵金属的现状；并对硫化镍试金富集贵金属的机理进行了探讨，晶体结构及贵金属硫化物和硅酸盐渣相化合物的热力学数据表明，在硫化镍相和渣相分离时，贵金属趋向于进入硫化镍相。引用文献54篇。     

Risk monitoring and early-warning technology of coal mine production

This article was written according to the secudty information theory and the secudty cybernetics basic principle, for reducing the accident risk effectively and safeguarding the production safety in coal mine. First, each kind of risk characteristic has carried on the earnest analysis to the coal-mining production process. Then it proposed entire wrap technology system of the risk management and the risk monitoring early warning in the coal-mining production process, and developed the application software-coal mine risk monitoring and the early warning system which runs on the local area network. The coal-mining production risk monitoring and early warning technology system includes risk information gathering, risk identification and management, risk information transmission; saving and analysis, early warning prompt of accident risk, safety dynamic monitoring, and safety control countermeasure and so on. The article specifies implementation method and step of this technology system, and introduces application situations in cooperating mine enterprise, e.g. Xiezhuang coal mine. It may supply the risk management and the accident prevention work of each kind of mine reference.
