1.方法要点本方法用盐酸溶解钛铁试样,在铜的324.8nm共振吸收线上,于盐酸1％介质中用空气-乙炔贫燃火焰测定试样溶液的波高,铜标准系列在5μg/ml以下呈线性关系。本方法在Al~(3+)<200μg/ml、Ti~(4+)75μg/ml和Fe~(2+)100μg/ml条件下无干扰。用国内外标准样品和国家标准方法对照其结果很好。本 1. Method points The method of dissolution of ilmenite samples with hydrochloric acid, copper in the 324.8nm resonance absorption line, in 1% hydrochloric acid medium with air-acetylene lean flame test sample solution wave height, copper standard series at 5μg / ml The following is a linear relationship. The method has no interference in the condition of Al ~ (3 +) <200μg / ml, Ti ~ (4+) 75μg / ml and Fe ~ (2+) 100μg / ml. With domestic and international standard samples and national standards of control method, the results are good. this
