Study of the kinetics of biodegradation of tetraethylene glycol mono-n-octyl ether and tetraethylene glycol and simulation of the formation of some intermediates

Abstract

The biodegradation courses of the pure tetraethylene glycol mono-n-octyl ether and tetraethylene glycol using the mixed microbial culture under the static conditions are described. The formation of main intermediates in dependence on time was simulated by chosen kinetic models, differential equations and worked out programme. Both the decreases in the concentration of initial compounds and the increases in the concentration of formed metabolites in dependence on time were determined by means of analytical method. The analytical results in graphic form were compared with the data found by simulation of the biodegradation.
