摘要
在乙炔一空气火焰中,用吸收和发射测定原油、渣油等重质油品中的钠含量,认为用发射法既可节省元素灯,又能提高测量精度。吸收和发射法的特征浓度分别为:0.015mg/L和0.009mg/L。
Determination of sodium in heavy oil has been studied by flame atomic absorption and emission methods in acetylenew-air flame. With emission, the method is considered to save a lamp and to increase the detection sensitivity. The characteristic concentrations of sodium by flame absorption and emission methods are 0. 015mg/L and 0. 009mg/L, respectively.
