Little-Cost Potentiometric and Spectrophotometric Procedures for Cephalothin Assessment in Pure and Biological Fluids.

Low-cost potentiometric and spectrophotometric procedures for cephalothin (CPI) determination in pure and biological fluids were investigated. The potentiometric technique is created through titration of CPI with an aqueous medium of 0.1 M NaOH at an ionic strength of μ = 0.

Developing Metal Complexes for Captopril Quantification in Tablets Using Potentiometric and Conductometric Methods.

Potentiometric and conductometric methods were successfully applied to elucidate the interaction of 10 ions, viz., Cr, Fe, La, Th, Co, Mn, Pd, Sr, Ti, and Zr, with the antihypertensive drug captopril (CAP) and its role to determine CAP in pure powder and tablet forms. The ionization constant of CAP and the generated complexes' stability constants (log ) were evaluated using potentiometric and conductometric methods at 25 ± 0.

A novel method for determination of magnesium in urine and water samples with mercury film-plated carbon paste electrode.

A square wave adsorptive stripping voltammetric (SWAdSV) method for the indirect determination of trace amounts of magnesium with thiopentone sodium (TPS) as an electroactive ligand, at carbon paste mercury film electrode (CP-MFE) is proposed. It is observed that the increase of the square wave voltammetric cathodic peak current of TPS, under alkaline conditions, is linear with the increase of Mg concentration. Under optimum experimental conditions viz.

Voltammetric determination of azithromycin at the carbon paste electrode.

Azithromycin (AZ) is the first member of a class of macrolide azalides antibiotics called azolides. A simple and selective square-wave voltammetric (SWV) method has been developed for the determination of azithromycin in pure form, in pharmaceutical preparation and in biological samples. Determination of azithromycin was accomplished with hand-make carbon paste electrode (CPE) in oxidative screen mode.

Square-wave stripping voltammetry for direct determination of eight heavy metals in soil and indoor-airborne particulate matter.

The application of square-wave voltammetry (SWV) for the determination of eight elements viz. Cd(II), Pb(II), Cu(II), Zn(II), Co(II), Ni(II), Cr(VI), and Mo(VI) in soil and indoor-airborne particulate matter has been examined and optimized. The cathodic and anodic types of the SWV technique were examined for the detection of these metal ions.

Potentiometric and spectrofluorimetric studies on complexation of tenoxicam with some metal ions.

The interaction of tenoxicam with six metal ions, viz. Fe(III), Bi(III), Sb(III), Cr(III), Cd(II) and Al(III) was studied using potentiometric and fluorimetric methods. In the potentiometric method the ionization constant of the ligand and stability constants of the complexes formed have been tabulated at 25+/-0.
