Erbium(Ⅲ) PVC membrane sensor based on N-(benzyloxycarbonyloxy)succinimide as a new neutral ionophore
摘要:
In this study, a new Er3+ 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 Er3+. 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 Er3+ ions spiked in tap and river water samples.
