In this work, adsorption kinetics were investigated in order to remove the acid blue 62 off the aqueous solutions using mesoporous silicate SBA-15 loaded with tannic acid (tannin-SBA-15). Nitrogen adsorption and desorption test (BET), X-ray diffraction (XRD) and Fourier transform infra-red spectroscopy (FT-IR) analysis characterize synthesized composite. The impacts of some parameters such as P...

A number of enzyme digestion assays show apparent first-order kinetics of reactant depletion. There are four possible explanations of this phenomenon: (i) the reaction is dominated by a first-order limiting step, (ii) the digestion follows a pseudo-first-order kinetics under the excess of a reactant species, (iii) the first-order kinetics is only applicable to the slow transient of the reaction...

in this research project, the nitrito nitro isomerization of [co (nh3)5no2]f2 complex has been studied. isomerization of this complex in the solid state follows a first order kinetics. the rate of isomerization at different temperatures was determined using a fourier transform lnfrared spectrophotometer. ? and ? are calculated at 298 k. the infrared, visible and ultraviolet spectra of this comp...
