Determination of parts-per-million quantities of tellurium in various alloys by x-ray spectrometry

Ferrous metallurgy

“…In the vacuum X-ray spectrometric determination of ppm quantities of tellurium in steel, tellurium was separated by reduction and precipitation and the precipitate, separated on a membrane filter, was analyzed (78). TIN Spectrophotometric methods for determining tin in steel were reported using phenylfluorone (317, 327, complexing agents.…”
