simultaneous determination of uranium and thorium by second derivative spectrophotometry
Analyst, 1992Co-Authors: A Ramesh, J Krishnamacharyulu, L K Ravindranath, Brahmaji S RaoAbstract:A second-derivative Spectrophotometric method has been developed for the simultaneous determination of uranium and thorium using 4-(2′-thiazolylazo) resacetophenone oxime as the Spectrophotometric Reagent. The method allows the determination of uranium and thorium in the range 0–10.0 ppm. The relative error is less than 4%. Common anions and cations do not interfere in the determination even when present in large amounts. However, for transition metal ions, viz., Cu, Ni, Pd and Pt, the tolerance limit is less than 100 ppm.

sorption of cr vi by amberlite xad 7 resin impregnated with brilliant green and its determination by quercetin as a selective Spectrophotometric Reagent
Journal of Hazardous Materials, 2009Co-Authors: Mohammad Saeid Hosseini, Ahmad Hosseinibandegharaei, Haidar Raissi, Foroogh BeladorAbstract:A new chelating polymeric sorbent as an extractant-impregnated resin (EIR) has been developed using brilliant green (BG) and Amberlite XAD-7 resin. The BG-impregnated resin showed superior binding affinity for Cr(VI) in the presence of many co-existing ions and no considerable interference was observed. The influence of various physicochemical parameters on the recovery of Cr(VI) were optimized by both static and dynamic methods. The Langmuir adsorption isotherm gave a satisfactory fit of the equilibrium data. The kinetic studies performed for Cr(VI) sorption revealed that 93%, which confirmed accuracy of the measurements.
