In this study, for the first time we report a highly selective and sensitive lutetium ions chemical optical sensor based on immobilization of a asymmetrically S-N Schiff's base, namely N-(thien-2-ylmethylene)pyridine-2,6-diamine (TPD) on a triacetylcellulose membrane. This optode exhibits a linear range of 5.0 ×10 -7 -1.0 ×10 -5 M of the Lu(III) ion concentration with a detection limit of 9.3 ×10 -8 M at a wavelength of 336 nm. The influence of responsible factors for improving sensitivity of the sensor was studied and identified. Response time of the newly designed optode was within 20-30 s depending on the Lu(III) ion concentration. Response of the optical sensor is independent of the pH of the solution in the range of 3.0-9.0. It manifests advantages of fast response time, low detection limit and most significantly, very good selectivity with respect to a number of lanthanide ions. The sensor can readily be regenerated with thiourea solutions and its response was reversible and reproducible. This optode was applied to the determination of Lu(III) in aqueous and CRM samples.

“…In last few years, it has been presented as a very useful technique to build up two-beams Fabry-Perot (also called Fizeau) nanocavities on optical fibre with lengths less than a micrometer [15]. Simplicity or reproducibility are the main advantages this method offers respect to other deposition techniques employed to develop optical fibre sensors such as for example sol-gel [16,17], dip coating [18] or Langmuir-Blodgett [19].…”

Objectives: An optical chemical sensor membrane obtained by physical inclusion of a 2-nitro-6-(thiazol-2-yl-diazenyl)phenol (NTDP) as a selectophore and polymethyl methacrylate (PMMA) and 2-nitrophenyl octyl ether (NPOE) as a plasticizer. Methods: The adsorption of Lu(III) causes the colour of the membrane to change from orange to pink with maximum absorbance (λmax) at 606 nm. The sensor membrane gives the best response towards Lu(III) ion at pH 6.5, after 10 min of contact time, at 150 ng mL -1 Lu(III), and 10 mL solution. Results: A linear Lu(III) calibration curve can be developed in the concentration range of 5.0-280 ng mL -1 with R 2 = 0.9990. The molar absorptivity is found to be 9.06 x 10 6 L mol -1 cm -1 . The detection and of quantification limits are found to be 1.63 and 4.95 ng mL -1 , respectively. Conclusion: The optical sensor membrane analytical characteristics was performed as interference of anions and cations, equilibrated time, reusability, detection limit, etc. and compared with the previous different conventional methods for Lu(III) using various chromophores. The optical sensor membrane investigated in this work was examined in real samples with excellent results comparing with the previous ICP-OES method.
