A SIMPLE AAS METHOD FOR THE DETERMINATION OF ZINC IN RED BLOOD CELLS FOR NUTRITIONAL APPLICATIONS / 营养学报

ABSTRACT

The zinc content in red blood cells has been proved to be a better index than either serum Zn or plasma Zn for nutritional and metabolic studies. A simple direct dilution method followed by AAS determination of Zn has been developed. The optimum dilution ratio is found to be 1 19 of deionized water. Recovery of this method is consistantly between 96-97% with a coefficient of variation less than 3%.
