This standard specifies the method for determining the rhenium content in rhenium compounds. This standard is applicable to the determination of rhenium content in rhenium compounds such as high rhenium acid (HReO4), potassium high rhenium acid (KReO4), and ammonium high rhenium acid (NH4ReO4). The measurement range is as follows: the rhenium content in high rhenium acid is 40.00 g/L to 90.00 g/L, and the rhenium content in potassium high rhenium acid and ammonium high rhenium acid is 40.00% to 70.00%.
This standard specifies the determination methods for the contents of sodium, magnesium, aluminum, calcium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, lead, zinc, zirconium, molybdenum, platinum, palladium, and rhodium in potassium rhenate (KReO4). This standard is applicable to the determination of the contents of sodium, magnesium, aluminum, calcium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, lead, zinc, zirconium, molybdenum, platinum, palladium, and rhodium in potassium rhenate. The determination range is as follows: sodium, magnesium, aluminum, calcium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zirconium, molybdenum, platinum, and palladium: 0.001% to 0.080%; lead, zinc, platinum, and rhodium: 0.002% to 0.080%.
