The qualitative and quantitative analysis of an antibiotic drug, 5-amino-1 cyclopropyl-7 (cis-3, 5 dimethyl-1-piperazyl)-6,8- dihydro-1, 4 dihydro-4-oxo-3-quinoline carboxylic acid (Sparfloxacin, SFX) and its pharmaceutical formulation i.e.sparx-100 tablet, has been done using polarographic and amperometric methods. Complexation behavior of SFX with Fe(II),(More)
Physicochemical, microbial and pharmacological studies on Fe (III)--Tamoxifen complex have been carried out in solid and aqueous phases. On the basis of elemental analysis, polarographic studies, amperometric titrations and IR spectral studies the probable formula for the complex has been worked out to be 1:1, Fe(III)--Tamoxifen. A tentative structure has(More)
Physicochemical, Microbial and Pharmacological studies on Fe(III)-Dacarbazine complex have been done in solid and aqueous phase. On the basis of elemental analysis, polarographic studies, amperometric titrations and IR spectral studies the probable formula for the complex has been worked out to be 1:1, Fe(III)-Dacarbazine. The metal ligand interaction has(More)
The electrochemical behavior of quinine was investigated by cyclic voltammetry (CV) and square wave voltammetry (SWV) using surfactant. The reduction peak current of quinine increases remarkably in presence of 1% CTAB. Its electrochemical behavior is quasi-reversible in the Britton-Robinson buffers of pH 10.38 by exhibiting the well-defined single cathodic(More)
Simple, rapid and accurate voltammetric methods viz. DCP, DPP and DPASV have been presented for the trace determination of gold and other transition metals in quartzite rock sample. The analysis has been performed using 0.1 M(NH4)2 tartrate, 0.1 M NaClO4 and 1 M NaOH as supporting electrolyte with 0.001% gelatin as maximum suppressor. The results show the(More)
Present communication deals with the synthesis of complexes of [N-(p-tolylsulphonyl)-N'-n butyl-urea], with certain transition metals viz. Cu(II), Zn(II), Fe(II) and Cd(II). Structures of all the complexes have been established on the basis of their consistent elemental and spectral analysis. Also, it reports their in vivo hypoglycemic screening on albino(More)
Direct current polarography and differential pulse polarographic methods have been developed for the qualitative as well as quantitative analysis of vitamin B1, B2 and B6. Thiamin (vitamin B1) produced a well-defined wave in 0.1 M KCl at pH 5.2 with E(1/2)=-1.2 V and E(p)=-1.22 V versus saturated calomal electrode (SCE). Riboflavin (vitamin B2) gave two(More)
Various diseases cause abnormalities in the composition of blood and urine by increase or decrease of concentrations of its constituents or through the appearance of new compounds therein. The analysis of blood samples obtained from a healthy individual and burns patients, for its cystine contents has been done successfully using direct current poloragraphy(More)
The electroanalytical behavior of Zn(II)-baclofen complex has been described by direct current polarographic (DCP) method. The complex of transition metal Zn(II) with baclofen, [4-amino-3(4-chlorophenyl) butanoic acid, has been prepared and characterized on the basis of elemental analysis, IR-spectral, polarographic and amperometric studies. The(More)
A convenient and accurate analytical procedure has been developed for the trace determination of bismuth(III) in natural waters and biological fluids. Bismuth gives a well-defined, diffusion-controlled cathodic wave in 1 M HCl with a half wave potential of -0.21 V with reference to a saturated calomel electrode. Trace amounts of Bi(III) have been determined(More)
