In this paper, a method of determination of the trace niobium in nickel alloy by inductively coupled plasma atomic emission spectrometry （ ICP - AES） is investigated. The effects of carrier argon flow rate, input power, observation height on the spectral-line intensity were also stu-died. And the sample is analyzed accurately. The method is high sensitivity, simple and rapid. It can be used in routine work.
