Abstract: Many industries such as paper, food, cosmetics, textiles etc. use dyes in order to color their products. The presence of these dyes in water even at very low concentration is highly visible and undesirable. Color is the first contaminant to be recognized. Photodgradtion technique offers a good potential to remove color from wastewater. In the prese... Show More

Abstract: Samples of Tilapia (Oreochromis niloticus) and African catfish (Clarias gariepinus) were collected from Hawassa and Ziway Lakes during March 1-20 of 2003 E.C. The moisture content of freeze-dried body of the fish collected from six sites ranged between 62.6% and 86.6% (m/m). An optimal procedure required 12 mL mixture of HNO3, HClO4, and H2O2 (3:2:...
