Abstract
|
|
|
|
An ion liquid chromatographic method was presented for the determination of copper, zinc, iron, and manganese in multi-vitamins formulations. An aliquot of the sample was dissolved in d-HNO3, The transition metals were chromatographed in PAR reagent delivery module and :u -Bondapak C,8 using 2.0mM 1-octanesulfonic acid sodium salt and 50mM tartaric acid adjusted to PH 3.4 with 50% NaoH solution. Reproducibility and precision (RSD) of copper, zinc, iron and manganese were 0.8/, 1,2%, 0.7%, and 0.8% respectively
