A method of simultaneously measuring contents of Al, Cu, Mn, P and Si in
ferrotitanium by utilizing an
inductively coupled plasma emission spectrometer is provided. The method includes (1) a step of preparing a
test sample solution, (2) a step of selecting element spectral lines, namely a step of selecting the optimum
spectral line of each element according to
substrate composition of a
test sample, (3) a step of mapping standard curves, namely a step of preparing standard solutions of the Al, the Cu, the Mn, the P and the Si, measuring emission
light intensity of each element under the optimum
spectral line by utilizing the
inductively coupled plasma emission spectrometer, and mapping the standard curves, and (4) a step of detecting the
test sample, namely a step of introducing the test sample solution to the
inductively coupled plasma emission spectrometer through a feeding
system, measuring emission
light intensity corresponding to each element, and determining the content of each element according to a corresponding
standard curve. The linear relations of the standard curves obtained by the method are good, measurement of contents of the elements is high in
accuracy and precision, and the method can be used for analyzing
standard samples and production test samples.
