Influence of the acidity iodous acid (HOIO) solution system on kinetics disproportionation reaction is examined in aqueous sulfuric (0.125 moldm-3 ). The rate constants were determined at 285, 291, 298 and 303 K based data obtained under stationary conditions. calculated increase with increasing temperature for different values iodate concentrations. average activation energy 46 kJmol-1 was cho...

Effect of hydrodynamic heterogeneity on micromixing intensification in a Taylor–Couette flow (TC) reactor with variable configurations inner cylinder has been investigated by adoption parallel competing iodide-iodate reaction system. Two types cylinder, circular and lobed (CTC LTC), were used to generate heterogeneity, focusing the effects Reynolds number, acid concentration, feeding time perfo...

An innovative, simple, and sensitive spectrophotometric method was described for the determination of cimetidine in both its pureform pharmaceutical formulations. By oxidizing 2.4-dinitrophenylhydrazine (2.4-DNPH) mixing it with analkaline solution, a brightly colored chromogen maximum absorption wavelength 586 nm is created. After that,spectrophotometry used to quantify amount cimetidine. Othe...
