Abstract

Water is necessary for the growth of humans and all other living things. Water is becoming scarce due to industrialization and its rapid growth, and the water ecosystem is negatively impacted by the direct release of wastewater into the environment. The textile, tanning, coating, plastics, paint, printing, and other industries, discharge dyes and pigments into the environment. One major problem is to remove dyes and pigments from industrial wastewater in a inexpensive and environmentally friendly way. Before they are released into the environment, there are several ways to mitigate the situation, including chemical, biological, and chemical oxidation processes. The advanced oxidation process (AOP) is a widely employed technique for eliminating contaminants from water and wastewater. The dye molecules are broken down by a Fenton and Fenton-like mechanism, in which the breakdown of hydrogen peroxide produces hydroxyl radicals. This chapter focuses on the most current advancements and various strategies used in the Fenton and/or Fenton-like processes used to degrade the dye molecules.
