Abstract
Environmental pollution is one of the greatest global problems that has a high nega-tive impact in all life aspects. It increases with time due to the rapid increase in the indus-trialization and growing human population which cause grave and irreversible global dam-age. The pollution of air, water, and soil are the three basic categories of environmental pollution.(1) Consequently, the protection of the environment becomes one of the most le-thal problems facing humanity.Water is considered one of the most essentials for human being, that must be safe, clean, and affordable. Although it is considered the most important substance on the earth where most of the earth surface is covered with, nowadays most sources of water such as river, seas, lakes and oceans are drained with different industrial wastes and chemical pollu-tants making it unsuitable for the essential purposes. However, industrial waste disposal pro-cess tends to comprise the quality of water for daily use despite the importance of clean wa-ter to society. On the other hand, chemical pollutants are related to discharge of industry sewage as synthetic dyes, excess use of pesticides, fertilizers in agriculture sector, pharma-ceutical residue, and land filling of domestic waste.(4-8) Among these chemical pollutants, organic dyes are serious contribute to water pollution. As most of dyes are difficult to de-compose in water since they have complex molecular structures that turn them to be more stable toward light and resistance to biodegradation.(9) The world-wide production of dyes is nearly 0.8 million tons per year(10) and the dyeing industry grows at an annual rate of 2%.
