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 present paper these methods were employed for removal of Tornasole RPe and Alizarin yellow G and the techniques were found to be very useful and cost effective for a better removal of dye and comparison between removal dye by hydrogen peroxide, ferrous sulfate, and silver nano particle in sun light effect. We obtain 100% of degradation of dyes.

Abstract: This paper presents a new method for separating Rhenium, Molybdenum, Vanadium and Tungsten ions on a thin layer of Perlite using the thin layer -electro-chromatography method. This method is based on the combination between chromatographic forces and electric forces by applying different voltages on the separation plate for different times using several electrolytes as different mobile phase concentrations, at different applying field duarations on the process. This method also shows the possibility of using Perlite as a thin layer in this kind of separation process, which can apply in the separation of other types of biochemistry and inorganic ions This relatively simple method is cost effective.

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 (3:2:1, respectively) to mineralize powdered samples in open refluxed digestion vessels: 0.5 g of the fish body. The concentrations of 3 toxic elements in the body of the fish determined by flame atomic absorption spectrophotometer varied, respectively, (mg of element/kg of fish); Cd = 0.4 - 1.85, Pb = 0.05 - 0.5 and Hg = 0.07 - 0.096. The concentration of those three heavy metals in water samples was also determined similarly by FAAS varied, respectively, as (mg of element/L of water sample); Cd = 0.06 - 0.66, Pb = 0.28 - 0.36 and Hg = 0.5 - 0.74. Application of the statistical t-test on heavy metal elements data has shown that there was a significant difference between the mean concentrations of Hg in water samples from the two Lakes. There is no significant difference between fish as well as water sample of the two lakes for the other metals.
