Simultaneous Determination of Traces of Lead and Cadmium in Various Samples by Differential Pulse Polarography after Adsorbing Their 1-(2-Pyridyazol)-2-Naphthol onto Microcrystalline Naphthalene
A highly selective, rapid and economical differential pulse polarographic method has been developed for the determination of trace amounts of cadmium and lead present together in various standard alloys and biological samples after adsorption of their 1-(2-pyridylazo)-2-naphthol complexes on microcrystalline naphthalene. Cadmium and lead complexes are equantitatively adsorbed on microcrysta...
متن کاملsimultaneous determination of zinc and lead in blood samples by differential pulse polarography
in present study we determine the zinc and lead levels in human blood samples by differential pulse polarography under optimum experimental conditions (ph=7.5, scan rate=5mv/s and pulse amplitude=50mv) the polarographic reduction peaks of zn and pb were examinedin the -0.72 v and-0.15 respectively. the zinc and lead content can be determined by in comparison with their standard solutions. accor...
متن کاملExtractive Differential Pulse Polarography of Mo (VI) Oxinate in Chloroform and its Application in the Determination of Molybdenum in Steel
The voltammetric characteristics of Mo (VI) oxinate at the mercury electrode, in the presence of tri-butylammonium perchlorate (tri-BAP) and piperidinium perchlorate (PP) + piperidine (P) as two different types supporting electrolytes, have been studied in chloroform. With the both supporting electrolytes a two electron irreversible process for the reduction of Mo (VI) oxinate was observe...
متن کاملdevelopment of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
Determination of triflumizole by differential pulse polarography in formulation, soil and natural water samples.
A novel electroanalytical procedure is proposed for the determination of the triflumizole in formulation, soil and natural water samples using differential pulse polarography (DPP). Triflumizole exhibited a single well-defined cathodic peak over the pH range of 1.0-9.0 in Britton-Robinson (B-R) buffers. The peak potentials were shifted to more negative values upon increasing the pH and a plot o...
