[ 1 ] - Highly selective and sensitive sensor based on 4,13-didecyl-1,7,10,16-tetraoxa-4,13-diazacyclooctadecane as a heterocyclic ionophore
A new polyvinyl choloride (PVC) membrane sensor for cerium (III) was prepared based on 4,13-didecyl-1,7,10,16-tetraoxa-4,13-diazacyclooctadecane (kryptofix22DD) as an ionophore. The sensor exhibites a linear concentration range of 1.0×10-6to 1.0×10-1M, with a Nernstian slope of 18.0±1.0 mV/decade, and a detection limit of 9.7×10-7M. It has a fast response time (5 s) and can be used for two mont...

[ 4 ] - LaCo0.5Fe0.5O3 Nanoparticles as a Highly Efficient Adsorbent for Rapid Removal of Trypan Blue Dye From Aqueous Media
Nanoparticles of perovskite-type LaCo0.5Fe0.5O3 (LCFO) were fabricated by sol–gel method.Thermal decomposition process of the complex precursor was examined by means of differentialthermal analysis–thermal gravimetric analysis (DTA/TGA). X-ray diffraction (XRD) resultsshowed that single perovskite phase has been completely formed after calcination at 750 °C. Inaddition, the surface morphology a...
[ 5 ] - New Coated Graphite Potentiometric Sensor for Selective Determination of Copper (II) Ions
A highly selective copper (II) coated graphite sensor was prepared by 1,13-bis(8-quinolyl)- 1,4,7,10,13-pentaoxatridecane (kryptofix 5) as a supramolecule ionophore into plasticized polyvinyl chloride (PVC) membrane. The best response characteristic was observed using the membrane composition of PVC = 30.0 mg, dioctyl sebacate (DOS) = 63.5 mg, palmitic acid (PA) = 3.0 mg and kryptofix 5 = 3.5 m...
