Abstract In this research, a strong anionic resin was prepared to remove chloride ions. This study performed in laboratory pilot evaluate effective parameters such as temperature, amine flow rate, pH, ion concentration and of caustic. The purpose work is determine kinetics the reaction determination optimal operating conditions order achieve maximum saturation. shows that volume distilled water...

the solutions of mathematical models for the estimation of the kinetic, and biokinetic parameters of naphthalene, anthracene and pyrene during degradation in surface and subsurface soils are presented in this work. the models were developed using the twin concepts of rate-determining step and steady-state approximation method. they described the biodegradation of single and a mixture of polycyc...

the charge-transfer complexation reaction between iodine and dibenzo- 18-crown- 6 (db18c6) has been studied spectrophotometrically in chloroform solution at different temperatures. the resulting donor-acceptor complex was formulated as (db 18c6…i )i . the spectrophotometric results , as well as the conductivity measurements, indicated that the gradual release of tiiodide ion from its contact io...

The cumulative reaction probability ~CRP! has been calculated for the H21OH↔H2O1H in its full dimensionality by using the centrifugal sudden ~CS! approximation for J.0. The Boltzmann average of the CRP provides the most accurate thermal rate constant to date for the title reaction on the Walch, Dunning, Schatz, Elgersma ~WDSE! potential energy surface ~PES!. It is found that the theoretical rat...

The stopped flow method has been used to determine the pH dependence of the kinetics of the binding of NADPH to chicken liver fatty acid synthase over the pH range 6.0-8.5. The kinetics is consistent with a one-step binding mechanism, and the pH dependence of the second order rate constant indicates that an ionizable group either on the enzyme or on NADPH with a pK, of 6.1 is of importance in t...

the use of colored semiconductor oxide like copper (ii) oxide and nickel (ii) oxide for photocatalytic bleaching of rose bengal was investigated in detail. in order to harness the solar energy, the effective wavelength of the photocatalyst is to be expanded into the visible region and that increases the rate of photocatalytic bleaching of the dye. progress of the reaction was observed spectroph...
