The reaction between hexamethylenediisocyanate and 1-pentanol in toluene was studied by means of reversed-phase liquid chromatography. By employing this method, it was possible to determine all components of the reaction mixture including both products, i.e. N-(6-isocyanate hexyl)pentylcarbamate and N,N'-bis(pentyloxycarbonyl)hexamethylenediamine. Relations for the calculation of kinetic constants were derived assuming a competitive consecutive second-order reaction. It was demonstrated that the reaction involved in this case is indeed a second-order reaction, and the rate constants of the first and second consecutive reactions were determined.

Thermodynamics and kinetics of the reaction between thyroxine and antithyroxine antiserum has been studied using the concentration and temperature conditions usual in the radioimmunoanalysis. The reaction is assumed to be homogeneous and of the second order. Because of the initial concentrations of thyroxine and of the free bonds of the heterogeneous population of antibodies present in the used antiserum the rate constant equation for second-order reaction has been used in the integrated form. The relative rate constants have been obtained and the activation energy of the reaction in absence of the serum proteins in the reaction mixture or, respectively, in the presence of the euthyroidic serum has been calculated. The nature of the effect of so-called deblockators (J) (8-anilino-1-naphthalene sulphonic acid and tiomersal) on the reaction rate and on the change of the reaction enthalpy (or entropy) has also been investigated. The association constant of this reaction has been evaluated from the radioimmunoanalytical data transformed by the Scatchard relation, modified for the conditions of thyroxine radioimmunoanalysis.

Nitrogen removal from environment is significant due to its effect on health and the whole ecosystems. Hence a highly nitrogen tolerant aerobic denitrifier, Pseudomonas stutzeri AZ101 was isolated from aquaculture wastewater and characterized using 16S rRNA analysis. The ability of the isolate to carry out simultaneously nitrification and denitrification (SND) was investigated. Different initial concentrations of nitrate and ammonium were used to determine the rate of SND. The denitrification data fitted well with the second order reaction kinetics with correlation coefficient between 0.923-0.9588. The nitrification data does not fit to both first and second order reaction kinetic but progressive shifts in the logarithm phase of the growth were observed at different initial concentrations. The kinetics data provide a significant insight to nitrogen removal from the wastewater.
