needs a methodology for extracting nickel from chocolates

[kwokskan]

I would be most grateful if anyone can help. I am hoping to extract nickel from chocolate bars for analysis but I do not have the exact protocol for the extraction. The chocolate will need to be digested with conc nitric acid but hydrogen peroxide is also required in a Teflon vessel. The final extract will be analysed on a mass spectrometer. Can anyone help with the exact methodology for the extraction. Many thanks.
