“…Fenton's reagent is cheap and easy to handle compared to other reagents. The decomposition of Fenton-like reagent is presented in the following equations [80] ( ) The iron(III) reacts with hydrogen peroxide to form iron (III) peroxo complex. The complex is decomposed to produce iron (II) then it reacts with hydrogen peroxide to yield the oxidant, hydroxyl radicals.…”

Dyes are complex organic compounds which are used by various industries to colour their products. These dyes are purged from various industrial sources such as textile, cosmetic, paper, leather, rubber and printing industries. Wastewater effluents contain dyes which may cause potential hazards to the environment. Some of these dyes are toxic, carcinogenic and can cause skin and eye irritation. Therefore, many researchers have been studied the effectiveness of dyes removal from aqueous solution by different separation methods. Different separation techniques have been used for the treatment of dye-bearing wastewater such as adsorption, coagulation/flocculation, advanced oxidation technologies, ozonation, and membrane-filtration, aerobic and anaerobic degradation. All dye separation techniques have their own limitation in terms of design, operation efficiency and total cost. This review paper provides extensive literature information about dyes, its classification and toxicity together with various treatment methods into dye adsorption characteristics of several non-conventional cost effective sustainable adsorbents. The mechanism and the effects of various physio-chemical process parameters on dye adsorption are presented here.

“…The classic Fenton oxidation showed some features [13], as nonselectivity oxidation derived by hydroxyl radical (·OH) generated from H 2 O 2 with Fe(II) [14], fast reaction rate, low cost, and low toxicity of reagents used. However, the homogeneous Fenton process also showed some significant drawbacks, such as the additional amounts of Fe 2+ increasing the formation of ferric hydroxide sludge [15], and the narrow available range of solution pH values (2)(3)(4) [16]. In order to overcome these drawbacks, the heterogeneous Fenton-like reaction is considered as a more practical and efficient alternative technique [17].…”
