【摘要】 本文试验研究了以乙酸丁酯萃取浮选测定0.1～1μg磷的最佳条件,以及分离耐热合金中共存元素简便的,易于掌握的方法。应用这方法可以灵敏、准确的测定耐热合金中10^-4％磷。更多还原

【Abstract】 Extraction flotation of associated substance of phosphomolybdate-crystal violet is done in a sulfuric acid medium with butyl acetate. The calibration curve is linear for 0-0.8gP/10ml and the molar absorptivity is eS9Snm=2.7x105.This method has been applied for the determination of trace P(0.0001%) in superalloy.更多还原
