| Abstract: | In this paper,We have determinde trace Cu and Fe in beer by enhancing effect of sur-factant and organic solvent-FAAS. We have studied the influences of surfactant and or-ganic solvent and have studived mechanism. In fact, this method was statisfied, recoveryratios were between 97.8% to 111% ,enrichment factors of Cu was 2.1 times,Fe was 1.9thimes. |
