A Scientific Article
Mrs. Dean of the College of Education for Pure Sciences, Prof. Dr. (Hamida Idan Salman), obtained the acceptance to publishing a scientific article upon the title (Adsorption of sulfate pollutants from water on the surface of Dihydroxide Nanolayers) by the Scientific Articles Committee at Karbala University after fulfilling all publication conditions. The Dean of the College stated that water is one of the elements of the environment and an essential element in sustaining life and that any change in its natural composition is considered a pollutant and poses a threat to living organisms directly or indirectly and threatens their safety. Polluted water is defined as water that is chemically or physically polluted, which causes damage to aquatic life and water consumers, including humans, animals, and plants. Physical pollution is the result of physical factors such as heat, radiation, and biological factors, which are due to the presence of microorganisms (germs) present in the water and they are highly dangerous to live, especially those that cause diseases. As for chemical pollutants, they are either dissolved or suspended in water, and the latter occurs as a result of throwing chemicals into sea and river waters, and usually, domestic wastewater and industrial water are the main cause of chemical pollution and there are many types of materials Chemical pollution in river water and this pollution is a change in the chemical and physical properties of water. Chemical pollution in the aquatic environment is caused by the presence of organic compounds such as acids and alkalis. Industrial waste in some industries, such as acid-containing batteries, is one of the most common causes of chemical pollution. The most common form of water pollution with organic compounds is due to the presence of proteins, fats, and other compounds. These pollutants reach the water through wastewater or industrial waste, and there are also some inorganic compounds in a free form such as mercury, lead, and other compounds. The other reason for chemical pollution is the presence of many inorganic pollutants causing pollution that may be present in water systems, including positive ions that represent heavy metals, which are dangerous and toxic to life, and negative ions are also dangerous such as phosphates, nitrates, and sulfates, and cyanides, etc.
