High-efficiency removal of lead/cadmium from wastewater by MgO modified biochar derived from crofton weed

Sulfonated graphene oxide impregnated cellulose acetate floated beads for adsorption of methylene blue dye: optimization using response surface methodology

“…Water pollution is considered one of the most important critical problems facing countries, since wastewater poses a significant threat to the ecosystem as well as human health 1 . One source of contamination is dye discharge from industries such as textile, paper, leather tanning, food processing, plastics, cosmetics, rubber, printing and dye manufacturing 2 – 4 .…”

Biochar and bio-oil fuel properties from nickel nanoparticles assisted pyrolysis of cassava peel

“…Generally, the production of biochar and bio-oil can be conducted from different waste biomass sources such as almond shell, corn cob, rice husk, sugarcane bagasse, groundnut shell, poplar sawdust, food waste, Crofton weed, citrus peel, coffee husk, palm kernel shell, walnut shell and cassava rhizome ( Cheng et al., 2021 , 2022 ; Egbosiuba et al., 2020a ; Ifa et al., 2020 ; Islam et al., 2021 ; Kalair et al., 2021 ; Morales et al., 2021 ; Nkomo et al., 2021 ; Promraksa and Rakmak, 2020 ; Quillope et al., 2021 ; Rueangsan et al., 2021 ; Saleem, 2022 ; Selvarajoo et al., 2022 ; Soka and Oyekola, 2020b ). The quality of the biochar can be determined by physicochemical parameters such as volatile matter, percentage carbon content, fixed carbon, ash content and higher heating value (HHV).…”

Effective Removal of Basic Red 46 with Ti3C2 Powder Modified with Citric acid

“…Where Q e (mg/g) and Q m (mg/g) were the equilibrium adsorption capacity and maximum adsorption capacity, respec- ChemistrySelect tively, K L (L/mg), K F [(mg⋅g À 1 )/mg⋅L À 1 ) 1/n ] and K T (L/g) denoted in turn the adsorption coefficients of Langmuir, Freundlich and Temkin, n and C e (mg/L) represented the adsorption strength and the equilibrium concentration, B T was adsorption heat. [34] By comparing the linear relationship among Langmuir, Freundlich and Temkin, it can be clearly seen that the Langmuir model (R 2 = 0.999) was closer to 1, being more consistent with the adsorption process than the Freundlich model (R 2 = 0.93685) and the Temkin model (R 2 = 0.98262). For the reason that the adsorption process of basic red 46 by CA-Alk-TC-6 was on the uniform medium surface.…”

“…As a result of the improper treatment and discharged variously toxic organic and inorganic pollutants and metal ions and so on which mainly were caused via fast urbanization and industrialization, [1] water pollution has already turned into an inevitably vital ecological environmental issue. [2] The inappropriate emission of some harmful chemicals into water such as organic dyes derived from food, textiles, plastics will bring about severe harm to human beings, animals, ecology and plants.…”
