Indirect Determination of Ascorbic Acid by Atomic Absorption Spectroscopy
A new and simple method followed by atomic absorption spectrometry has been developedfor indirect determination of ascorbic acid (AA). The proposed method was based on the oxidationof AA to dehydroascorbic acid with Cu2+cation(200mgL-1)in an ammonium thiocyanatesolution atpH2.4. AA reduces Cu2+to Cu+followed by the precipitation of Cu+ with SCN-. Then, the excess ofCu2+in the solution was measu...

متن کاملThe determination of metals in blood serum by atomic absorption spectroscopy-II Magnesium
The magnesium content of blood serum may be accurately determined by atomic absorption measurements. Analysis can be carried out on as little as 0.05 ml of serum and the only preliminary treatment necessary is dilution of the sample with water containing about 1 per cent of ethylenediaminetetracetic acid or of strontium chloride. Existing methods for estimation of magnesium THE lack of detailed...
متن کاملThe determination of metals in blood serum by atomic absorption spectroscopy-I
Abstm&-The celcium content of blood mrum cm be accurately determined on 0.1-0.25 ml samples by atomic absorption measurements in an air-acetylene flame after removal of the proteins by coagulation and centrifuging. A fairly accurate value can be obtained more quickly from direct measurements on serum diluted with water, which may with advantage contain about 1 per cent of the disodium salt of e...
متن کاملDetermination of aluminum in bone by atomic absorption spectroscopy.
In developing this method for determination of Al in bone we paid special attention to the homogenization of bone samples, which presents great difficulties for trace-element analysis. To minimize the risk of contamination, we preferred low-temperature ashing over classical wet-digestion techniques for destruction of the organic material. Graphite-furnace atomic absorption spectroscopy is used ...
