Abstract A new procedure for the field characterization of the available amount of molybdenum in soil extract is described. It is based on the preconcentration of the Mo(V)-SCN– complex into toluene solution of N-octylacetamide (OAA) and subsequent heating of the extract for ≈ 10 min at 60° C over a water bath. The molar absorptivity of the complex is (3.50) × 104 1 mole–1 cm–1 at λmax 470 nm. The detection limit of the method is 4 ppb Mo. It provides a significantly increased tolerance limit for iron (up to 1000 ppm) and is applicable to the field characterization of Mo in soil extracts.
