An extraction method has been described 833 using a chloroform solution of N-n-methoxyphenyl-2-furohydroxamic acid as chromogenic reagent.Interference by iron, molybdenum, chromium, zirconium and tantalum is eliminated by the presence of stannous chloride.

    element. Dilute any unknown sample(s) if the measured absorbance is too large – i.e., outside of the range of the standards. (2) AAS Measurement of magnesium: Repeat procedure (1) using the magnesium stock solution and the unknown samples. Remember that the element selection on the AA (the drop down box) has to be changed to measure magnesium. Selenium occurs naturally in biological materials that vary from a few parts per billion to a few per cent. Methods for its determination, therefore, cover a wide range of concentrations. As a result...
