Hydrothermal carbonization synthesis of cassava slag biochar with excellent adsorption performance for Rhodamine B

Preparation of Mn2O3/MIL-100(Fe) composite and its mechanism for enhancing the photocatalytic removal of rhodamine B in water

“…To determine the suitable conditions for photocatalytic degradation of RhB using M100Mn, the affecting factors were investigated in a range of solution pH (2)(3)(4)(5)(6)(7)(8)(9)(10)(11), photocatalyst dosage (0-1000 mg L À1 ), RhB concentration (15-50 mg L À1 ), and Na 2 S 2 O 8 concentration (100-500 mg L À1 ). To evaluate the reusability of the material, the photocatalyst was separated from the dye solution by centrifugation aer each reaction cycle and then washed with water and ethanol to remove the RhB on the surface of the catalyst.…”

“…1,2 Wastewater containing dyes is difficult to treat due to the persistent and complex structure of the dyes, which resist conventional biological treatment such as aerobic and anaerobic processes. As alternatives to biological treatment, physicochemical processes for the treatment of RhB have been studied extensively, including adsorption, 3,4 photocatalysis, [5][6][7][8][9][10] electrochemical-Fenton, 11 biological treatment, and ltration. 12 Among them, advanced oxidation processes, particularly photocatalysis, are usually considered as some of the most suitable techniques for the treatment of RhB and other dyes due to their being highly efficient, low-cost, and environment-friendly techniques.…”

Wu et al, 2020 A adsorção de iodeto de hidrogênio nas superfícies de carbono N-livres e N-dopados foram estudadas por TFD e hydrochar foi sintetizado a partir de cascas de coco. X.…”

Surface Charge Effects on Adsorption of Solutes by Poplar and Elm Biochars

“…Since wood biochar is both carbon-containing and porous, this makes it an excellent candidate for water filtration applications and this is an active area of research [4][5][6][7]. Wood is one of many different renewable biomass feedstocks for biochar, other low-cost materials being studied for filtration applications include algae [8], seaweed [9], crab shells [10], and cassava slag [11], just to name a few.…”
