A method is provided for direct determination of uranium in the organic phase (TBP, TOPO, alkyl phosphonate, or alkyl quarternary amine-secondary alcohol in kerosene)by differential derivative oscillopolarography with a Model

本文报道宁在A1660型示波极谱仪上,采用差示导数示波极谱法,首次使用碳粉-氯化钾-琼胶作为盐桥,外接饱和甘汞电极,以异丙醇-铜铁灵-乙酸-乙酸铵-氨三乙酸组分为底液,直接测定有机相(膦类或胺类萃取剂)中的铀。本方法简易快速,取样量少,无需破坏有机相并省略反萃及除氧手续。铀的峰电位为—0.28伏特(相对饱和甘汞电极),铀浓度在2.0~10.0微克/毫升范围与波高呈线性关系。实测样品的相对标偏(测定次数n=6)为±5%,回收率为96~104%。

A new method for the determination of compositions of Ba-Y-Cu-O and Ba(Sr)-La Cu-O superconducting thin films by ICP-AES is described. In this method, the internal stan- dard is selected from the determined constitueats of the sample and by means of determining a set of mass ratio values of the analyzed elements to the internal standard element, the percentage contents of each analyzed elements can be calculated. There is no need to weigh and dilute the sample accurately. The method is flexible and simple. Analytical...

The (104) planes diffraction instensitv of Dolomite and cal-cite vary with different grinding times (different particle size). The experimental results showed that integrated intensity reduces by forty percent after one hour by manual grinding. In order to eliminate the particle size effect, the sample particle size should be controlled strictly so that the standard sample and test sample particle sizes are identical. For bigger particle size (70-40 micrometer), higher precision and accuracy are also obtainable...
