Following the global water crisis, advanced countries have different methods to solve this issue. The industrial pigment is one of the first recognizable contaminants and creates an unfavorable appearance. Synthetic dyes are used in a wide range of advanced technologies, including paper, plastics, rubber, leather, food production, cosmetics, textiles, and dyeing. Several methods have been proposed to remove these materials. These methods include membrane filtration, coagulation, advanced oxidation, ozonation, electrical-coagulation, and adsorption, photocatalyst. All of these methods have their advantages and disadvantages. Among these methods, adsorption and degradation by photocatalytic hydrogels has been confirmed compared to other methods due to low cost and simplicity of operation and has one the best performance in removing pigment from effluents, and one Technology is effective. Photocatalytic and Polymeric superadsorbents are considered appropriate for retrieving and removing metals and metal cations due to their features such as unique structure, reasonable price, ease of use, reusability, and high chemical and mechanical resistance.
