“…The use of magnesium nitride to absorb F or HF was not recommended. Pansare and Mulay (315) pyrolyzed the sample in a stream of nitrogen, employing platinum-rhodium as catalyst, and converting CO to C02 with copper oxide at 300°C. Mlinko (285) used an improved ter Meulen procedure: sample passed over palladium, then nickel, and finally copper to yield water.…”
