Sulfadiazine-potentiometric sensors for flow and batch determinations of sulfadiazine in drugs and biological fluids.
New PVC membrane electrodes for the determination of sulfadiazine (SDZ) are presented. The electrodes are fabricated with conventional and tubular configurations with a graphite-based electrical contact, and no internal reference solution. The selective membranes consist of bis(triphenylphosphoranilidene)ammonium.SDZ (electrode A), tetraoctylammonium bromide (electrode B), or iron(II)-phthalocy...

15 صفحه اولDirect potentiometric determination of sodium ion in blood. I. Potentiometric response in simple sodium chloride solutions.
We measured the emf of NaCl solutions (120-160 mmol/L) with a home-built cell in steady-state and with some commercial direct potentiometric analyzers about 20 s after the sample is introduced into the instrument. We compared the results with the theoretical sodium ion activity calculated according to different thermodynamic theories. The slope of the calibration graph was calculated with and w...
متن کاملPotentiometric Study of Pyocyanine
Bacillus pyocyaneus produces, according to the conditions, different varieties of pigment of which pyoeyanine is best known and easily isolated because of its solubility in chloroform. This pigment is indigo blue at alkaline reaction, wine-red at acid reaction, and is reducible to a leuco compound by various reductants or in the absence of air by the living bacillus itself, and the leucodye is ...
