“…From preliminary experiments it has been established that the most stable performance of the ISE (potential reproducibility) is achieved at 5% w/w of QAS. The effect of the neutral anion carrier content on the analytical characteristics of ISE reversible to doubly charged inorganic ions, including selenate ions, was studied in Reference 23 , and it has been demonstrated that the optimum content of the neutral carrier is 20% w/w. The rest of the membrane, i.e.…”

A new film selenate selective electrode has been developed, with the following membrane composition: (3,4,5-tris-dodecyloxybenzyl)tetraoxyethyl trimethyl ammonium chloride (5% w/w) as an electroactive component, (poly)vinyl chlorid (33% w/w) as a membrane matrix, 1-bromonaphtalene (42% w/w) as a plasticizer, (4-trifluoroacetyl) benzoic acid heptyl ester (20% w/w) as a neutral anion carrier. The electrode characteristics are as follows: linear range -2•10 -6 -10 -2 М by Na 2 SeO 4 ; line plot slope 26,0±0,3 mV/decade; lower detection limit 1•10 -6 М by Na 2 SeO 4 ; working рН range 2,15 -6,3; potential drift 0,9 mV/h; response time 15 -90 s; selectivity in presence of chloride, bromide, sulfate and other ions; lifetime up to 3 weeks. The electrode developed has been tested on model solutions using the standard addition method in the calibration plot variant, and bracketing technique.

Membrane composition of molybdate-selective electrodes based on higher quaternary ammonium salts has been optimized. It is found that the best analytical characteristics of electrodes are based on 3,4,5-tris-dodecyloxybenzyl) tetraoxyethyltrimethyl ammonium in chloride form (5% w/w) with the addition in membranes of the solvating additive (neutral carrier) − p-heptyl ester 4-trifluoroacetylbenzoic acid (TFABAHE, 20% w/w). Their analytical characteristics: low detection limits (1•10 −6 mol/l); logarithm selectivity coefficients relative to interfering chloride -1,-4, sulfate -0.8, bromide -0.7, tungstate -0.9 ions; working range of pH (8.5−9.5); slope of the electrode function (24.4 mV/decade) are determined. Sodium molybdate aqueous solutions has been studied with FT-IR spectrometry method at various pH. In sodium molybdate solutions at pH greater than 8.0-8.5 hydrolytic processes are mild. However, using a molybdate-selective electrodes is better to use freshly prepared solutions. This increases the reproducibility of the experimental results. The proposed electrode was employed to determine of molybdate ions of model water samples using the calibration plot method.

“…This complicated analysis process limits the field deployment applications of phosphate sensors without the aid of chemical reagents and makes phosphate sensors only applicable in the laboratory. Phosphate sensors have been proposed and devised for working with various mechanisms such as solid electrochemical redox types [ 5 ], liquid membrane-ion selective electrodes (ISE) [ 6 ], solid-state ISE [ 7 , 8 ], spectrophotometric, and photoluminescence types [ 9 , 10 , 11 ]. However, there are several difficulties in developing phosphate sensors.…”

Phosphate sensors have been actively studied owing to their importance in water environment monitoring because phosphate is one of the nutrients that result in algal blooms. As with other nutrients, seamless monitoring of phosphate is important for understanding and evaluating eutrophication. However, field-deployable phosphate sensors have not been well developed yet due to the chemical characteristics of phosphate. In this paper, we report on a luminescent coordination polymer particle (CPP) that can respond selectively and sensitively to a phosphate ion against other ions in an aquatic ecosystem. The CPPs with an average size of 88.1 ± 12.2 nm are embedded into membranes for reusable purpose. Due to the specific binding of phosphates to europium ions, the luminescence quenching behavior of CPPs embedded into membranes shows a linear relationship with phosphate concentrations (3–500 μM) and detection limit of 1.52 μM. Consistent luminescence signals were also observed during repeated measurements in the pH range of 3–10. Moreover, the practical application was confirmed by sensing phosphate in actual environmental samples such as tap water and lake water.
