| Popis: |
A new titrimetric method for the microdetermination of mercuric mercury is described. The proposed method is based on the fact that aqueous l -ascorbic acid solution reduces mercuric mercury to mercurous mercury; itself being oxidized to dehydro- l -ascorbic acid. The mechanism of the reaction is discussed. The proposed method is simple, rapid, and sufficiently accurate to determine concentrations as low as 100 μg of mercuric mercury. The experimental error does not exceed ±2%. The method was also used for the determination of corrosive sublimate in such biological fluids as urine or milk with an error not exceeding ±10%. |
