A determination of manganese in plant material by atomic absorption spectroscopy using a methanol-aqueous solvent combination.

Hiebert, Gregory Lee. (2012-12-11)

The effect of various organic solvents upon the absorbance of manganese was investigated. Methanol was found to give the greatest enhancement in sensitivity of the solvents analyzed. The plant material was dry ashed t ...
Determination of mercury by flameless AAS.

Lowrance, Gary. (2013-01-07)

DETERMINATION OF MERCURY BY FLAME LESS AAS The procedure outlined describes an extremely sensitive and accurate method for the determination of mercury down to 50.0 ppb in solution. The procedure has been adapted to ...
The determination of zinc in plant material by atomic absorption spectroscopy: a comparison with the accepted AOAC colorimetric method.

Hall, Michael J. (2012-12-11)

A method for determining zinc in plant material by atomic absorption spectroscopy has been developed. The proposed method utilizes .1 N HCl-99% methanol as the solvent system and is consistent with the requirements for ...
