摘　　要：建立灰化消解-电感耦合等离子发射光谱法测定含油水中的铅、镉、铬、镍、钒金属含量。探讨了样品前处理条件。用(1+19)的硝酸做为酸性介质,在工作曲线的线性范围内,线性良好,γ值可达到0.9995以上。对含油水样的测定精密度好,相对标准偏差不超过3%,可用于各类含油排放水金属含量的测定。A method for the determination of lead, cadmium, chromium, nickel and vanadium in oily water was establishen by inductively coupled plasma atomic emission spectrometry. The pretreatment conditions were dis- cussed. （ 1 ＋ 19） nitric acid as an acidic medium, in the linear range of the working curve, good linearity, γ value can reach more than 0.9995. The accuracy of the determination of oil-like water samples is good, the relative stan- dard deviation does not exceed 3%, can be used for all kinds of oil-containing water content determination.
