摘要:

Iron (II) oxide in silicate rocks can readily be measured after digestion with HF and HCl by reaction with KI and KIO3. The iodine produced during the digestion is trapped in CCl4and measured at 512 nm spectrophotometrically. Results for ten accepted and two new geochemical reference standards are presented.
