Studiu comparativ privind capacitatea de autopurificare a sistemelor acvatice în prezenţa nicotinamidei şi a furfuralului [Articol]

Abstract

In this work we studied the self-purification capacity of natural waters in the presence of nicotinamide and furfural with type application modeling - microcosms. The results showed the buffering capacity of the lake water is able to lessen the impact of acid-base nicotinamide and furfural. The water self-pu rification mechanism works effectively analyzed by redox processes. Substrate degradation occurs with the participation of oxygen. Both nicotinamide and furfural and their transformation products decrease with radical self-purification capacity of natural waters. Furfural has a more pronounced negative impact on self-purification capacity of lake waters near the lake. It was established that hydrogen peroxide result in an increase of oxygen free radical red ox process of self-purification step.
