The fluorescent sodium salt of amoxicillin was used for the detection of heavy metals in aqueous solutions. It was found that Copper and Silver has a quenching effect on the fluorescence of amoxicillin. Cu2+ ions were detected in aqueous solution up to 1x10-7 M and Ag1+ ions up to 1x10-6 M. Hg2+ ions were also detected in aqueous samples but in high concentration. http://pubs.sciepub.com/ajn/1/2/3/ajn-1-2-3.pdf sodium salt of amoxicillinfluorescencemetallic sensing
