“…As a result, design of an inexpensive and simple technique, which can provide the necessary selectivity to determine Lu(III) in the presence of other lanthanides that are very similar to Lu(III) is of great value. Optical sensors, besides Lu(III) potentiometric ion-selective electrodes which have been already reported [13][14][15][16] , can be proper for the Lu(III) assessment, as they may easily be incorporated into low cost, easy to use kits. Furthermore, they can offer the required selectivity and sensitivity for the environmental monitoring [17][18][19][20][21][22] .…”

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.

“…The sensitivity and selectivity of the ion selective electrodes depend significantly on the membrane compositions [7]. Addition of appropriate amount of plasticizer leads to improve the electrochemical properties of conventional ISEs [6]. The right plasticizer leads to a better polymeric membrane and can form a high selectivity ISE.…”

Ion selective electrode (ISE) is an electrode that has been designed to identify heavy metal ion in a solution. In this experiment, thiazole-4-carboxamide (Th) is used as ionophore and sodium tetraphenylborate (NaTPB) as an additive. Polyvinyl chloride (PVC) was used as a polymeric matrix in the membrane selective electrode. Different type of commonly used plasticizers is analysed to choose the one with the best response. There are four types of plasticizer used; dioctyl phthalate (DOP), dibutyl phthalate (DBP), benzyl acetate (BA) and nitrobenzene (NB). The ratio (w/w)% used for all plasticizers Th:PVC:NaTPB:Plasticizer is 5.0:30.0:2.0:63.0. ISE is used in a sample solution with different concentration to figure out the best plasticizer. Ion selective membrane using BA gives the best response with 19.3±1.4 slope value, while ion selective membrane using DOP gives the least response with 11.3±0.7 slope value.

“…Ion-selective electrodes (ISEs) are well known for fast response, simple analytical procedure, and relatively low cost, and have found widespread utilization in clinical and environmental analyses [1][2][3][4]. The electrodes with a solid-contact configuration (SC-ISEs) have made very rapid progress in the past decades.…”
