| dc.description.abstract | Textile wastewater consumes large quantities of water and produces large volumes of wastewater which is often rich in color, containing residues of reactive dyes and chemicals as well as much more hard-degradation materials. The presence of dyes in wastewater poses an environmental concern due to the existence of toxic components that may impact to aquatic and non-aquatic life. In this work, a new environmentally sound and low-cost, yet highly efficient nanopyroxene, (NaFeSi2O6) which is known as aegirine, will be used as an adsorbent for the removal of a model molecule dye from aqueous solutions and real textile wastewater by the batch-adsorption technique. Different diluted samples (100%, 85%, 70%, 55%, 40%& 25%) for COD test and (100%, 80%, 60%, 40% & 20%) for the UV- spectrophotometer were prepared and adsorption was done at 25 oC, 35 oC and 45oC. The samples were put in the shaker for 24 hour and 150 rpm and separate by centrifuge at specific time and speed. The results were measured by COD and UV- Spectrophotometer devices. The readings of COD must decrease but they were randomly changed maybe due to the high total suspended solid. Also for the UV- Spectrophotometer the results before adsorption were corrected as the dilution factor decrease the absorbance were decreased but for the samples after adsorption the absorbance were randomly changed and that unreasonable, this indicates that there is a specific metal in the water sample didn’t adsorb by nonopyroxene at wavelength equal approximately 281nm. According to the results the adsorption isotherm and thermodynamics study cannot applied. | en_US |
