Abstract:A new method f o r the determination of molybdenum and tungsten i s described based on their catalysis of the hydrogen peroxide-iodide reaction a s monitored with a n iodide ion-selective electrode. method yields better results than methods previously used. example, Yatsimirskii and Afanaseva and Erdey and Svehla have found a lower limit of 0. 0 2 and 0. 1 p g / m l f o r molybdenum I n the present work a s little as 0. 004 pg/ml of molybdenum and tungsten is determinable.

“…Four procedures (42)(43)(44)(45) were reported for molybdenum based on its catalytic effect on the oxidation of iodide by hydrogen peroxide. In the first, Feys, Devynck, and Tremillon (42) followed the reaction by an enthalpimetric method.…”

“…A mathematical model of this reaction was constructed and the optimum analysis conditions were selected by Ruzinov (44). In the final procedure, Altinata and Pekin (45) followed the rate of the reaction with an iodide-activity electrode. Jost et al (46) described the determination of molybdenum(VI) from its catalytic enhancement on the reduction of brómate by iodide.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
