“…4 Therefore, a variety of strategies have been employed for the surface functionalization of PVC-based materials such as chemical reactions, plasmaion beam, and electric discharge treatments. [4][5][6][7][8] Since some special instruments are prerequisites for the plasma-ion beam and electric discharge treatment approaches, chemical reactions are considered to be a more facile approach for the surface modification of PVC-based materials. 4 Due to the simplicity of the chemical structure of PVC, it is not easy to introduce functionalities into PVC efficiently.…”

“…To the best of our knowledge, rarely any reports in the literature are available that describe the employment of fluorescent chemosensors for Sr 2+ ion detection in water . Furthermore, the detection limit of the present sensor is lowest among all the previously reported sensors for the Sr 2+ ion. − In present work, our goal is to develop a fluorescent probe which detects Sr 2+ ions in water and further investigate the practical utility of this sensor toward the detection of Sr 2+ in tap water, river water, and in toothpastes used in oral care.…”

A pyrene-based polymer, 2, was synthesized via one step condensation reaction between pyrene-1-carboxaldehyde and polyamine in methanol. Organic nanoparticles (ONPs) of polymeric compound 2 were developed using a reprecipitation method and investigated for their chemosensor application using fluorescence spectroscopy. Nanoaggregates of polymer compound 2 exhibit efficient and selective chemosensor properties for detection of strontium ions in an aqueous medium, with a detection limit of 9 nM. To analyze the practical utility of the sensor, it was successfully employed to detect the amount of Sr2+ in tap water, river water, and strontium based toothpastes.

“…The sensors' potentiometric selectivity coefficient values toward various cationic species were calculated and summarized in Table 3. Generally, the selectivity coefficients point out to which extent an interfering ion (j) can affect the sensor's response towards the primary ion, where selectivity coefficient values below 1 indicate the sensor preference for the primary ion [37]. The lower the values of the selectivity coefficient, the less influence the interfering ion will have on the measured potential.…”

New potentiometric membrane sensors have been designed to measure Th 4+ ions using two derivatives of 18-crown-6-ether as neutral ion-carriers. The membrane composition was optimized through a multi-stage process regarding plasticizers, lipophilic ionic additives, and ion-carrier content and the corresponding sensors' performance characteristics were investigated. The optimized sensors exhibited a Nernstian behavior for Th 4+ ions over wide working concentration and pH ranges. The sensors' repeatability, reproducibility, and reversibility were tested under the optimal conditions. The selectivity studies indicated the selective behavior of the developed sensors towards Th 4+ ions with respect to various mono, di, and trivalent ions. The sensors possess a fast response time and can work for at least 12 weeks without significant changes in their sensitivity. Th 4+ ions concentration in water samples was directly assessed by the developed sensors with good recovery and relative standard deviation values indicating the accuracy and precision of the developed sensors. Moreover, the obtained results were in a good agreement with those obtained by the spectrometric method.
