Co(II)Ofloxacin complex has been synthesized and screened for its physicochemical, microbial as well as pharmacological activity have been done in solid and aqueous phase. On the basis of elemental analysis, polarographic studies, amperometric titration and IR spectral studies the probable formula for the complex has been determined at 30±1C and ionic strength of μ= 1.0[KCl]. Raper’s paper disc...

Complex formation between a natural polysaccharide – gellan and an antimicrobial drug ofloxacin was studied in aqueous solution. Conductimetric potentiometric titration curves revealed that forms water-soluble complex of composition 2:1 mol/mol stabilized by ionic hydrogen bonds. The the gellan-ofloxacin confirmed FTIR spectroscopy, dynamic light scattering, zeta-potential thermogravimetric ana...

Understanding the carbon dioxide (CO2) solubility in formation brines is of great importance to several industrial applications, including CO2 sequestration and some capture technologies, as well CO2-based enhanced hydrocarbon recovery methods. Despite years study, there are few literature data on for low salinity range. Thus, this distilled water aqueous ionic solutions NaCl, MgCl2, CaCl2 MgCl...

New colorimetric receptors R1 and R2 with varied positional substitution of a cyano and nitro signaling unit having a hydroxy functionality as the hydrogen bond donor site have been designed, synthesized and characterized by FTIR, 1H NMR spectroscopy and mass spectrometry. The receptors R1 and R2 exhibit prominent visual response for F- and AcO- ions allowing the real time analysis of these ion...

VALIDATION OF A FOOT-AND-MOUTH DISEASE ANTIBODY ELISA IN FIVE LATIN AMERICAN COUNTRIES. The work plan consisted of using a liquid phase blocking ELISA test for the detection of antibodies to foot-andmouth disease virus (FMDV) using the following categories of sera: (A) Spot test 120 non-infected/non-vaccinated bovine sera diluted 1:32; (B) Titration test: 120 bovine sera from animals vaccinated...

Earlier proposed a general approach using data mV/mL from a potentiometric titration is tested for the quantitative determination of mixtures of monoand poly-protic substances. The method is based on the treatment of the primary data with nonlinear regression procedure using commercial software which gives directly the analytical result. A general formula valid for every type of acid base titra...

Ti/PbO2/Sb2O3 electrode was used as indicator electrode in potentiometric and conductometric titration in aqueous solution at 298 K. The E-pH curve is linear with a slope of 0.0505 V/dec at 298 K which is close to the theoretical value 2.303RT/F (0.059 V at 298 K). The standard potential of this electrode, E, is computed with respect to the SCE as reference electrode. The recovery percentages f...
