Optical pH Sensor Based on Quinizarin for Alkaline pH Regions
The development of an optical pH sensor based on immobilization of quinizarin (1,4-dihydroxyanthraquinone) on a triacetylcellulose membrane was described. The resulting membrane exhibited fast color change from yellow to violet, while changing the pH in alkaline region. The immobilized quinizarin showed a broader dynamic range from (pH 9.4-11.4) with respect to free form (pH 8.8-10.4). The sens...
متن کاملA novel sensor based on a heterocyclic ionophore for cerium (III) analysis in real samples
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 1.0×10-6 to 1.0×10-1 M, with a Nernstian slope of 18.0±1.0 mV/decade, and a detection limit of 9.7×10-7 M. It has a fast response time (5 s) and can be used for two m...

متن کاملOn the Determination of Creatinine and Creatine in Urine
Ever since the introduction of the calorimetric method for the determination of creatinine, potassium bichromate, in half normal solution, has been used as the standard for measuring the color obtained in the reaction of creatinine with picric acid and sodium hydroxide. That the bichromate has been serviceable for the purpose is evidenced by the fact that no other standard has ever been propose...
