Steel and iron — Determination of molybdenum content — Thiocyanate spectrophotometric method

Aciers et fontes — Détermination des teneurs en molybdène — Méthode spectrophotométrique au thiocyanate

Abstract / scope

This document specifies a thiocyanate spectrophotometric method for the determination of molybdenum contents in steel and iron. The method is applicable to molybdenum mass fractions between 0,005 % and 0,125 %.

Vanadium and tungsten interfere with the measurement if, because of their contents, the V/Mo ratio is greater than 16 or the W/Mo ratio is greater than 8.
