ANALYTICAL METHOD FOR THE DETERMINATION OF IRON IN MERCURY (ABSORPTIOMETRIC- THIOCYANATE)

Technical Report · Thu Jul 30 04:00:00 EDT 1959

OSTI ID:4195608

The impurities present in the mercury are oxidized with compressed air at an elevated temperature and obtained as an acid solution by passing the mercury in the form of a very fine spray through a dilute solution of nitric acid. The iron in the acid solution of the impurities is determined absorptiometrically as the ammonium thiocyanate complex. The method is applicable to the determination of iron in mercury containing from 5 to 150 mu g of iron per 100 g of mercury. Concentrations outside this range can be determined by suitable adjustment of the sample aliquot. (auth)
