Poly(vinyl chloride) based membranes of 5,7,7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradeca-4,11-diene diperchlorate and 3,5,7,7,10,12,14,14-octamethyl-1,4,8,11-tetraazacyclotetradeca-4,11-diene with dibutyl phthalate (DBP) dioctyl (DOP) as plasticizing solvent mediator show a Nernstian response for Cu2+ ions over wide concentration range (1 × 10–5–1 10–1 mol l–1) between pH 1.9 5.2. These electrodes have been found to be chemically inert adequate stability, time less than 30 s. The...
Uranyl ion selective electrodes have been constructed from poly(vinyl chloride) matrix membranes containing neutral carrier, 2,3,11,12-dicyclohexano-1,4,7,10,13,16-hexaoxacyclooctadecane and organic resin, 2,4-dihydroxypropiophenoneoxime–formaldehyde using dibutyl phthalate dioctyl as plasticizing solvent mediators. These demonstrate linear response to UO2+2 ions in the concentration range 10–5–10–1 mol l–1 with a Nernstian or near slope at pH 3. The are inert towards acids, salt solutions...
Spherical silica nanoparticles (n-SiO 2 ) with controllable size have been synthesized using tetraethoxysilane as starting material and ethanol solvent by sol-gel method. Morphology of the particles was controlled through surfactants. Sorbitan monolaurate, sorbitain monopalmitate monostearate produced varying sizes (80-150 nm), indicating effect chain length surfactant. Increase in non-ionic surfactant resulted decreasing particle nanoparticles. Further, also NH 3 base catalyst. These were...
Abstract Poly(vinylchloride) (PVC) and polystyrene based uranyl ion‐selective electrodes have been constructed using 2‐hydroxyacetophenoneoxime‐thiourea‐trioxane resin as electroactive material. For PVC membranes dibutylphthalate (DBP) dioctylphthalate (DOP) were used plasticizing solvent mediators. These membrane work in the concentration range of ca. 10 −5 –10 −1 M with a response time fast 30 s. The useful working pH is 2.5–3.5 perform satisfactorily up to 20 % (v./v.) partially...
Preparation of dispersed, amorphous, spherical silica nanoparticles using cationic surfactant as organic template, tetraethoxysilane (TEOS) precursor and ammonia catalyst has been carried out sol gel process. The aim the present study was to evaluate simultaneous effects on textural structural properties nanoparticles. We used a series surfactants, dodecytrimethylammonium bromide (DTAB), tetradecyltrimethylammonium (TTAB) cetyltrimethylammonium (CTAB) chain length grain size can be finely...
