The review aimed to identify differences and similarities in the adsorption process of five azo dyes [congo red (CR), reactive black 5 (RB5), methyl orange (MO), II (OII), (MR)] on natural materials, biosorbents, industrial agricultural waste, or biomass, which are alternatives costly activated carbon locally available. were characterized compared based their molecular structure weight, water solubility, acid dissociation constant, n-octanol-water partition coefficient, maximum absorbance. RB5 CR diazo dyes, whereas MO, OII, MR mono-azo dyes. anionic is an dye, direct dye. CR, RB5, MR, OII molecules contain one more sulfonate functional group(s), but does not. We performed a literature following parameters: initial dye concentration, adsorbent dosage, pH, temperature, isotherm, kinetic models, thermodynamic parameters, synergetic competitive interactions. tended adsorb best acidic medium at higher temperatures. concentration dosage studies indicated importance using appropriate amount for effective removal. follow Langmuir isotherm pseudo-second-order model. Most processes endothermic spontaneous, leading increase randomness solid-liquid interface. These results indicate between Relevant mechanisms assumed be electrostatic forces, hydrogen bonding, π–π interactions, among others. Nevertheless, focus lies development characterization not study influences from matrix “industrial wastewater”. Therefore, research needed develop units application textile industries.
