| Abstract: | Optimum conditions for the AAS determination of Fe?Cr?Ni and Co in a detergent composing H_2O_2 and citric acid are studied and reported in this paper. For all these elements, a recovery of 100% ?10% is obtained for the concentration range of 0. 5~5mg ?L~(-1). RSD obtained for the determination lies between 6% ~ 10%. |
