| Abstract: | A routine method has been developed for simultaneous determination of Ca, Mg, Al, Fe,
Cu, Zn, Mn, Ba, Ni and Y by ICP-AES, The wheat flour sample was digested with HNO_3-
HClO_4. in a Teflon beaker.
The effects of spectral interferences caused by Ca, Mg and Fe matrices on Cu, Zn, Ni,
Ba and Y were d'sscussed.
The interference coefficients of the elements were determined and used to correct the spe-
ctral interferences, The results were satisfactory |
