Spectrofluorimetric determination of arsenic(III) using dansylated peptide

The potential of dansylated peptide in determination of arsenic(III) was investigated. Fluorescence intensity of dansyl-D-Ala-Gly-OH (DAG) was quenched during addition of arsenic(III) in aqueous solution. The fluorescence spectrum of DAG was measured at pH 12 with excitation and emission wavelengths...
