Cu(II) Ion- Selective Membrane Electrode Based on bis(N-salicylidene-3,3'-diamino diphenyl) sulfone

In order to study the Cu(II) ion selective electrode, an optimized membrane was prepared by mixing of 30 mg of PVC powdered, 5 mg of considered ionophore, 60 mg of plasticizer and 5 mg of additive. The sensor showed a near Nernstian response for Cu(II) ions over a concentration range from 1.0×0-6 –1.0×0-2 M with a slope of 28.90.5 mV per concentration decade with a working pH range of 3.5-6.3. ...

Sn (II) Ion- Selective Membrane Electrode based on Dibenzo-18-Crown-6

We found that dibenzo-18-crown-6 (DB18C6) can be used as an ionophore to make a tin (II)-ionselectivemembrane electrode. The electrode exhibits a near Nernstian response for Sn2+ ions over aconcentration range from 1.0× 10-6 – 1.0× 10-2 M with a slope of 27.5 ± 0.6 mV per concentration decadein an acidic solution (pH=1). The limit of detection was 8.0× 10-7 M. It has a response time of < 20s an...

Comparative investigation on the correction factors of hydrogen permeability on CNTs-Mixed matrix membrane

This paper discusses different important gas permeation models such as “Maxwell”, “Bruggeman”, “Lewis-Neilson”, and “Pal” models to predict “Mixed Matrix Membranes” (MMMs) performance. The main parameter considered and discussed is the permeability of Hydrogen on Carbon Nanotubes (CNTs)-MMM. For evaluation of the theoretical models, experimental data of permeability for H2 were compa...

Studies on crystal semi-permeable membrane. II. On the formation of barium sulfate semi-permeable membrane.

The 1st report1) in a series of these studies, which was deduced from the report by Miyamoto and Takikawa2) that a precipitate of calcium silicate and magnesium silicate formed a semi-permeable membrane at the Pringsheim'a equilibrium point, recognized a formation of the so-called •hCrystal semi-permeable membrane•h also in a common water-insoluble salt (In this case, sodium carbonate and calci...
