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~(-6)to 1.0×10~(-2)mol/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 ions.It can be used in the pH range of 2.5-10.6 without any considerable divergence in potentials.The proposed sensor was successfully applied for the recovery of Er~(3+) ions spiked in tap and river water samples.

The sensor exhibits linear response with a Nernstian slope of 20.5 ± 0.4 mV / decade in The concentration range of 1.0 × 10 -6 to 1.0 × 10 -2 mol / L of Er 3+ has a very short response time (<10 s) and the 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 ions. It can be used in the pH range of 2.5-10.6 without any considerable divergence in potentials.The proposed sensor was successfully applied for the recovery of Er ~ (3+) ions spiked in tap and river water samples.
