Abstract
This work is presented as a continuation of our previous work where optimum time and power were studied to determine the chemical oxygen demand in standard solutions prepared from potassium hydrogenphthalate using a microwave oven. A gradual digestion in microwave oven was compared with conventional oven digestion at 150±2°C during 2 hours. The method was applied to urban and industrial wastewater coming from different sources of the Alicante province. The organic load in urban wastewater is variable due to the contribution of different industrial sources. Samples were digested in an oven according to the traditional method, as well as in a microwave oven applying different times and powers between 100 and 300 watts. The method was checked to be more effective if microwave digestion was carried out working with different and gradually higher powers than working with a high, fixed one. The analytical method that we propose is appropriate for samples of varied sources, such as urban and industrial wastewater.
