| Abstract: | Inductively coupled plasma emission spectroscopy was used to determine the contents of iron, nickel and vanadium in ethylene cracking tar, Dry-ashing method was used to treat ethylene tar, the analytical spectral line and integral time were optimized. This method is simple and accurate, and the relative standard deviation is less than 2%, the recovery rate is 97% to 103%. |
