Research:










DOMAINS OF INTEREST:

* Kinetics of Complex Reactions
* Numerical treatment of experimental data
 

CURRENT PROJECTS:

* Optimization of a continuous stirred reactor with high performances regarding macro and micro-mixing, for studies of chemical systems in transient and stationary period
* Obtaining and fitment of kinetic curves for studied systems in different experimental conditions (batch and continuous reactors, temperature, pH, presence of catalysts and modulators)
* Estimation of kinetic parameters for studied systems: phenols auto-oxidation; oxidation of phenols catalyzed by some enzymes present in natural medium (tyrosinase, peroxidase, catalase) and transition metal ions usually sloped in waste waters
* Computer modelling of the enzyme kinetics in batch and continuous reactors
