Sustainable Evaluation of Using Nano Zero-Valent Iron and Activated Carbon for Real Textile Effluent Remediation

Recent advances in dye and metal ion removal using efficient adsorbents and novel nano-based materials: an overview

“…The B-nZVI showed great removal results 99% of Cr 6+ at 250 rpm and 35 °C with 50 mg L −1 initial concentration of Cr 6+ . In a comparative study, 2 the concert of using nZVI and AC was examined for the removal of color from real textile wastewater. The results showed the enhanced color removal for the two examined adsorbents reached 84% for the AC and 80% for the nZVI at same operating conditions 0.8 g L −1 dose and 20 min contact time.…”

“…If these dyes are not properly handled, they can remain stable in the environment for long time, causing significant health impacts. 2 For instance, hydrolyzed Reactive Blue 19's (RB19) half-life is about 46 years at 25 °C and pH 7. 3 Moreover, most of them contain chromium in their molecular structure, which is carcinogenic.…”

“…Furthermore, it can cause serious side effects to human beings, such as renal failure and liver damage. 2,6 On the other side, rapid industrialization causes excessive release of heavy metals into the environment and thus causes a global concern because of their chronic toxicity. Cadmium, manganese, arsenic, mercury, chromium, cobalt, copper, lead, iron, vanadium, molybdenum, bismuth, and nickel are often present in industrial wastewaters and originate mainly from mining activities, battery manufacture, metal plating, petroleum refining, pesticides, tanneries, smelting, pigment manufacture, paint manufacture, photographic industries, and printing.…”

Disinfection of corona and myriad viruses in water by non-thermal plasma: a review

“…Those methods, on the whole, have significant disadvantages (Badawi et al 2021a ). One of these disadvantages is the contamination with disinfection by-products with carcinogenic consequences and environmental pollution (Su et al 2018 ; Badawi et al 2021b ). Chlorine, for example, interacts with organic chemicals to produce reactive chlorinated organic compounds that are toxic to people, and their treatment using UV irradiation takes a long time to be removed (El-Kalliny et al 2021 ).…”

Grafting of Acrylic Membrane Prepared from Fibers Waste for Dyes Removal: Methylene Blue and Congo Red

“…These were why non-conventional, safe, economically, and eco-friendly dyes removal-approaches "adsorption" was suggested by a lot of researchers, lately. Adsorption is a non-conventional method by which dyes may adsorb on the surface of the adsorbent material [16][17][18]. For instance, adsorption by natural polymeric substances is one of the most promising nonconventional approach and applicable methods for pollutants removal from contaminated wastewater [19,20].…”
