Özet
A new method for the determination of molybdenum and tungsten is described based on their catalysis of the hydrogen peroxide-iodide reaction as monitored with an iodide ion-selective electrode. This method yields better results than methods previously used. For example, Yatsimirskii and Afanaseva1 and Erdey and Svehla2 have found a lower limit of 0.02 and 0.1 μ.g/ml for molybdenum. In the present work as little as 0.004 μg/ml of molybdenum and tungsten is determinable.
