摘要: In this study, a highly selective and sensitive fluorescence assay has been proposed for the determination of copper(II) cobalt(II) ions in environmental water toner samples. presence hydrogen peroxide, reacted with new reagent Amplex® UltraRed (AUR), forming product only at pH 7.0, while AUR formed 9.0. The signal obtained was linear respect to concentration over range 1.6–12.0 μM (R2 = 0.988) 45.0 nM 1.0 0.992). limits detection (at signal-to-noise ratio 3) were 0.17 14.0 nM, respectively. Our present approach is simpler, faster, more cost-effective than other techniques samples that
