原子吸收分光光度法测定铟及铊文献上曾有过一些报导。由于矿石中铟及铊的含量都较低,因而在测定前必须事先进行萃取富集。本文主要是研究了铟及铊的萃取富集及其测定条件,并制定了硫化矿中同时测定铟及铊的方法。实验部分 (一)仪器及主要试剂原子吸收分光光度计:WFD-Y型,10厘米乙炔-空气燃烧器。铟、铊空心阴极灯均由我所自制,制作方法参阅文献〔4〕。铟标准溶液:由光谱纯金属铟配制,每毫升含铟25微克。铊标准溶液:由硝酸铊配制,每毫升相当于25微克铊。
Atomic Absorption Spectrophotometric Determination of Indium and Thallium There have been some reports in the literature. Due to the low content of indium and thallium in the ore, extraction and enrichment must be carried out prior to the determination. In this paper, we mainly studied the extraction and enrichment of indium and thallium and their determination conditions, and developed a method for simultaneous determination of indium and thallium in sulfide ores. Experimental part (A) of the instrument and the main reagent atomic absorption spectrophotometer: WFD-Y-type, 10 cm acetylene - air burner. Indium, thallium hollow cathode lamp by my self-made, see reference [4]. Indium standard solution: formulated from the spectrum of pure indium, containing 25 micrograms of indium per milliliter. Thallium standard solution: formulated from thallium nitrate, equivalent to 25 micrograms of thallium per milliliter.
