Abstract
A procedure using matrix‐compensated Mo standards to determine Mo in plant tissue by flameless atomic absorption is described. Concentration ranges of macroelements (N,P,K,Ca,Mg), microelements (Cu,B,Zn,Mn,Al,Fe), and HC1O4. typical of those found in HNO3‐HC1O4 plant tissue digests were examined for their effect on the observed analytical value of Mo. The mean of 20 Mo determinations of NBS orchard leaves SRM 1571 was 0.28 ± 0.01 ppm Mo compared to the NBS certified value of 0.3 ± 0.1 ppm Mo. Recovery of Mo added to digests of orchard leaves and alfalfa tops ranged from 95 to 105%.Keywords
