Нефтепродукты. Смазочные масла и присадки. Определение содержания фосфора в виде фосфомолибдата хинолина
Название (англ.):
Petroleum products; Lubricating oils and additives; Determination of phosphorus content; Quinoline phosphomolybdate method
Описание (англ.):
The method used is applicable to products containing any of the phosphorus compounds in normal use and having contents between O,OO5 and 1O,O % (m/m). The method is free from most interferences because the high insolubility of the quinoline phosphomolybdate precipitate leads to constant composition and freedom from most adsorbed or occulated impurities, especially from cations which would otherwise interferein the subsequent titration of the precipitate.
