Dear all,
I want to know the effect of temperature on electro oxidation of pharmaceutical effluent?
Dear Bhuvana,
Generally increasing the temperature results in an increase in the pharmaceutical degradation. An example is illustrated in the following paragraph:
Effect of temperature on phenol degradation
The electrochemical reaction of phenol is highly temperature dependent and shows that an increase in temperature will strongly facilitate the degradation of phenol. Fig. 7 shows a series of experimental runs performed at different temperatures say 40, 45, 50, 55 0C. A temperature of 55 0C could improve the degradation to high level after 3 hrs of electrolysis period. The rise of temperature as enhanced the molecular motion velocity and catalytic activity of the electrodes, which in turn speeds up the reaction. At temperature of 55 0C the degradation was higher when compared
to 40 0C as shown in Fig. 8. An increase in the temperature led to more efficient process. However, there is no need for heating wastewater at much higher temperatures in practical application due to increase in energy consumption. Similar results were obtained for phenol degradation, i.e. complete removal of phenol 98% was achieved during the first 3 hrs duration. Higher temperatures appear more detrimental to phenol degradation than do lower temperatures.
Therefore it might be convenient to operate at higher temperatures for the complete removal of phenol. The main influence of the electrolysis temperature on the degradation system was the production of hydroxyl radical and the catalytic activity of the electrode.
