摘要
研究了硫酸铵-1(2吡啶偶氮)2萘酚磺酸-Tween80体系萃取铁的行为。试验表明,当溶液pH20～40,能使Fe(Ⅱ)与Zn(Ⅱ),Cd(Ⅱ),Mn(Ⅱ),Mg(Ⅱ),A(Ⅲ)定量分离。应用该法测定了铝合金中Fe的含量,结果满意。
In ammonium sulfate-1 (2 pyridyeazo) 2 naphthol sulfonic acid(PAN-S)-Tween 80 system, the liquid-solid extraction behaviour of iron was investigated. The results indicated that the complex of Fe(Ⅱ) with PAN-S was almost completely extracted from the buffer solution(pH2 0-4 0) by Tween 80, while Zn(Ⅱ), Cd(Ⅱ), Mn(Ⅱ), Mg(Ⅱ), Al(Ⅲ) were not extracted This method has been applied to determine iron in aluminium alloys with satisfactory results.
