THE most commonly available of the thiol-acids is thioglycolic acid, also known as mercapto-acetic acid. This reagent is favoured by analytical chemists in research and industry1–3 for the colorimetric estimation of iron in micro-quantities because of certain advantages it offers4,5. In this Laboratory this reagent had been used in the annulus method for separation and detection of chromium and titanium on a filter paper6.
