Abstract

Using sodium deoxycholate as a protective medium, the selective recognition of Cu(II) at ng ml(-1) level is realized through dynamic phosphorescence quenching of 1-bromo-2-methylnaphthalene (BMN) without deoxygenation. The limit of detection is 4.32 ng ml(-1), and the relative standard deviation is 1% at 10 microM, linear up to 1 x 10(-5) M.
