Rare metallic concentrates. Methods for the determination of phosphorus pentoxide

Концентраты редкометаллические. Методы определения пятиокиси фосфора

Status: Effective - Supersedes. The limitation of the effectiveness period has been lifted: Protocol No. 7-95 of the IGU dated 01.03.95 (IUS 11-1995)

The standard applies to rare metal concentrates and establishes spectral methods for the determination of elements (in terms of oxides).

Стандарт распространяется на редкометаллические концентраты и устанавливает фотометрические методы определения пятиокиси фосфора (общего) в концентратах: ильменитовом (при массовой доле от 0,05 до 0,5 %) и рутиловом (при массовой доле от 0,05 до 0,3 %), ниобитовом (пирохлоровом) (при массовой доле от 0,05 до 1 %), цирконовом (при массовой доле от 0,05 до 0,3 %), лопаритовом (при массовой доле от 0,05 до 0,5 %) и пятиокиси фосфора, находящегося ввиде аппатита в концентратах: лопаритовом (при массовой доле от 0,05 до 0,5 %) и черновом(пирохлоровом) (при массовой доле от 2 до 20%).
