Nickel - Meteorite Separation

  1. Oct 30, 2011 #1
    Hi everyone! I'm looking to separate nickel from a meteorite sample and I have a pretty solid plan... however I'd like to know if there are any disadvantages of using the following methods:

    Quinoxoline Complexation with Spectrophotometric Determination (using pre-separation to remove interferences)

    Quinoxoline Complexation with Spectrophotometric Determination (using multiple absorbance measurements at multiple wavelengths and standards for any interfering species to determine the amounts of both nickel and interferents)

    Dimethylglyoxime Precipitation and Determination by Gravimetry

    Any advice would be appreciated!!!
