A polyvinylchloride membrane sensor based on N,N'-bis(salecylidene)-1,2-phenylenediamine (salophen) as membrane carrier was prepared and investigated as a Al 3þ -selective electrode. The sensor exhibits a Nernstian response toward Al(III) over a wide concentration range (8.0 Â 10 À7 -3.0 Â 10 À2 M), with a detection limit of 6.0 Â 10 À7 M. The potentiometric response of the sensor is independent of the pH of the test solution in the pH range 3.2 -4.5. The electrode possesses advantages of very fast response and high selectivity for Al 3þ in comparison with alkali, alkaline earth and some heavy metal ions. The sensor was used as an indicator electrode, in the potentiometric titration of aluminum ion and in determination of Al 3þ contents in drug, water and waste water samples.

“…There are many detection methods being reported to monitor Cu 2? , and responsive signals based on the optical absorption or emissions have been paid much attention [8,9]. It is well accepted that the fluorescent chemosensors have great advantages of high sensitivity, promptness, and easy operation [10,11].…”

A novel benzene sulfonamide-appended silica precursor has been designed and it played dual roles. Firstly, typical green emissions derived from f-f transitions have been achieved through its complexation with terbium ions. Secondly, the hydrolysis-polycondensation process that leads to new organic-inorganic hybrid material has been realized by its reactive trimethoxysilane unit. Different microstructures, controllable synthesis, and their photophysical properties were investigated. Importantly, these novel nanosystems were demonstrated to be capable of monitoring Cu 2? in terms of sharp luminescence changes.
