The Lecturer in the College of Education for Pure Sciences/Department of Chemistry, Professor Dr. (Munir Abdel-Aali Abbas), obtained the acceptance to publish a scientific article titled (Water Treatment Using Catalysts as Adsorbents) by the Scientific Articles Committee at the Presidency of Karbala University, after the article fulfilled all publication conditions. (Prof. Dr. Munir Abdel-Aali Abbas) mentioned that the world is facing a major challenge today as a result of drought, the lack of suitable water, the increase in population and human growth, and the development of agriculture and industry, which led to the deterioration of safe water and an increase in water pollution, which is known to be the presence of chemicals or Unwanted organisms that cause damage to the aquatic ecosystem in which they are located. There are many direct and indirect sources of water pollution in a large and large way, represented by chemical pesticides, the manufacture of textiles, paper, plastics, dyes, the manufacture of medicines and cleaning products, the synthesis of organic compounds and toxic heavy elements that dump their waste into the nearby rivers. These pollutants cause a great danger when they are introduced to the aquatic ecosystem (river stream) because they are not easily removed due to their high stability and high solubility as well. This prompted the invention and discovery of highly efficient techniques to remove pollutants from water and increase the proportion of safe water. Where these technologies can be divided into three main sections: * Chemical treatments such as (filtration, sedimentation flocculation, coagulation, flotation flocculation, electrocolouring, electrocoagulation (EC), and depigmentation of industrial effluents) these methods cause a secondary pollution problem due to the accumulation of colored sludge that is difficult to dispose of in addition to the high costs and Excessive use of chemicals in general. * Biotechniques: Using living organisms to transform pollutants into safe and harmless raw materials. The third main technology is the physical techniques represented by membrane filtration, reverse osmosis (RO), nanofiltration (NF), ion exchange and radiation, electrodialysis, photocatalysis, and adsorption, which are widely used in industrial scale, especially in wastewater treatment. Hygienic for textiles due to its high dye removal potential and low operating costs.
