“…A higher surface area means more ions diffuse and are attached to the resin. Different cationic and anionic resins are used to remove ionic dyes, such as methylene blue, methyl orange, and malachite green [54]. However, the removal efficiency of the ion exchangers relies on several factors, such as the concentration of the dyes in the targeted aqueous solution, and the amount of the ion exchangers.…”

“…Basically, the removal percentage of ionic dyes from contaminated water increases with decreased concentration of dye and increased amount of resin. Recently, anionic ion exchangers have been used widely to remove azo dyes from wastewater [54]. Although the ion exchange process has shown great performance in eliminating different types of pollutants from water, it is considered a very expensive process.…”

Rapid growth in various industrial fields has introduced a series of new environmental risks. The textile industry is one of the major industries that is influenced by rapid advancements in technological sectors. The development in textile dying technologies has presented new types of dyes that are toxic to the ecosystem. Azo dyes are the main artificial dyes used in textiles, food, and other applications. Typically, these dyes are introduced into the environment as wastewater discharged from factories. The discharged influence penetrates the ecosystem and causes deadly diseases to human and animals. Several studies present activated carbon as a proper solution to eliminating the presence of azo dyes in the environment. However, various types of azo dye have different properties and chemical structures. Thus, there is a crucial need for more studies on the application of activated carbons to eliminate the presence of azo dyes in the environment. This paper discusses the toxic effects of azo dyes on the environment and human health. Moreover, this work presents a general review of the preparation of activated carbon and the parameters that influence the adsorption performance.

The application of dyes in textile colouration has existed for centuries. Dyes are obtained from both natural and synthetic sources. Synthetic dyes are manufactured from chemical compounds and have been placed on a high pedestal in the textile industry due to their improved colour fastness, varied range of pigments and easy application as compared to natural dyes. However, they have been identified to be harmful to the environment and human health by researchers. When effluent containing harmful chemicals like sodium sulphide is discharged into the environment improperly, they cause a lot of diseases and hinder smooth air flow. With current submissions made by researchers on synthetic dyes application as a backbone, this review throws more light on the dangers and benefits involved in the use of synthetic dyes in the textile industry. It also touches on waste management as far as textile dyes are concerned. The application of synthetic dyes, precisely vat, reactive and sulphur dyes are highlighted in the study. With the purpose of addressing appropriate means of curbing undesired hazards caused by textile wastes water, several technological approaches to effluent treatment such as Physical, Chemical and Biological are brought to light in the study. The study recommends the adaptation of waste management principles such as the 5R hierarchy to curb environmental harm caused by synthetic dye effluents.
