Comparative study of ozonation and ozonation catalyzed by Fe-loaded biochar as catalyst to remove methylene blue from aqueous solution

Selective dye adsorption by pH modulation on chemically modified nanopolyaniline by N-grafting of maleic acid

“…8(c). To find the bestfitting model, the X 2 and SSE values were determined from eqn (10) and (11) and are given in Table S2. † The Langmuir adsorption isotherm, which has a lower X 2 and SSE, better fits the adsorption.…”

“…To date, photocatalytic degradation, 6–9 chemical oxidation, 10 biological decomposition, 11–13 electrochemical treatment 14 and adsorption 15–18 methods have been proposed to eliminate MB dyes from effluents before discharging them to the environment. Among the above techniques, adsorption technology has advantages, such as its ease, high efficacy, insensitivity to the contaminant substance, and flexibility.…”

Activation of persulfate by iron‐loaded soybean straw biochar for efficient degradation of dye contaminants: Synthesis, performance, and mechanism

“…Advanced oxidation technology (AOP) has attracted much attention in the field of organic wastewater treatment because of its strong oxidation ability and wide application range. Traditional AOP technologies include Fenton technology, 14 ultrasonic oxidation, 15 ozone oxidation, 16 and others. However, these techniques have the limitations of short half‐lives, 17 high energy consumption, complicated preparation, and narrow pH range (optimal range pH = 2–3) in their applications 18 .…”

Efficient photocatalytic degradation of ultra-high concentration printing and dyeing wastewater using a SiO2/GCN nanocomposite

“…Wastewater treatment is required in order to control the printing and dyeing wastewater produced in printing and dyeing factories. In general, the following methods have been used to remove printing and dyeing wastewater: biological treatment (such as the activated sludge method 5 and anaerobic aerobic method 6 ), physicochemical treatment methods (such as adsorption 7 ), advanced oxidation technology (such as photocatalysis, 8 ozone catalysis, 9 piezocatalysis, 10 and Fenton oxidation 11 ), and membrane separation technology (such as reverse osmosis, 12 ultrafiltration, 13 and microfiltration 14 ). Photocatalytic technology is the most promising, cleanest, and energy-saving technology amongst these methods, and has attracted a lot of attention from scholars at home and abroad.…”
