Chemex (stream sediments) COL (W)- using pyrosulfate and dithiolcarbonate (dl = 4ppm)



Chemex, stream sediments; colorimetry using pyrosulfate and dithiolcarbonate (tungsten), determination limit = 4 ppm

General Methodology:

Tungsten was determined colourimetrically subsequent to a pyrosulfate fusion and a dithiolcarbonate complexing for the generation of the colour.
