用自制的高铼酸根选择电极,以硫酸铵—柠檬酸铵-醋酸-醋酸铵为离子强度缓冲液,采用校正曲线法直接测定了某工艺流程萃取原液、反萃取液及KReO_4产品中的铼。本文将利用资料的有关实验条件及有关结论来测定钼精矿中的铼。实验表明:对于钼含量>44％,而铼含量>0.0ⅹ％的试样,可采用校正曲线法直接进行测定;铼含量低达0.001％时,用格氏作图法测定仍能获得较好的结果。
Using self-made perrhenate selective electrode and ammonium sulfate-ammonium citrate-acetic acid-ammonium acetate as ionic strength buffer, the calibration curve method was used to directly determine rhenium in extraction solution, stripped solution and KReO_4 product of a certain process. This article will use the relevant experimental conditions and related conclusions to determine the rhenium molybdenum concentrate. Experiments show that: for molybdenum content> 44%, and rhenium content> 0.0% samples can be determined directly by the calibration curve method; rhenium content as low as 0.001%, the determination by the Grignard can still get better the result of.
