Abstract

The amounts of Zn,Cu and Mn in biological samples were measured by FAAS after digesting with HNO_3-HClO_4(4∶1,V/V).The relative standard deviations were between 0.65%? ?.40% with the recoveries of 97.3%—102.4%.The calibration curves were linear with good correlation coefficients(r0.998).The method was simple,rapid with satisfactory results.
