摘 要:In this study,a new Er^3+ sensor based on N-(benzyloxycarbonyloxy)succinimide(BCS) as a neutral carrier has been constructed. The sensor exhibits potential linear response with a Nernstian slope of 20.5±0.4 mV/decade in the concentration range of 1.0×10^-6to 1.0×10^-2mol/L of Er^3+.It has a very short response time(10 s),detection limit of 6.3×10^-7 mol/L and a good selectivity relative to a wide variety of other metal ions including common alkali,alkaline earth,heavy,and transition metal *** can be used in the pH range of 2.5-10.6 without any considerable divergence in *** proposed sensor was successfully applied for the recovery of Er^3+ ions spiked in tap and river water samples.
