Adsorption of aniline from aqueous solution using graphene oxide-modified attapulgite composites

Abstract

Adsorption is an efficient treatment method for aniline removal in water treatment.

Bioengineered Graphene Oxide Microcomposites Containing Metabolically Versatile Paracoccus sp. MKU1 for Enhanced Catechol Degradation

“…As shown in Figure 4 d, both GO and PGO adsorbed catechol efficiently with a maximal adsorption of 54.4 mg/g for GO and 81.2 mg/g for PGO at 18 h. There was a 42% increase in the maximal adsorption of catechol with PGO than GO. Similar observations have been already reported in aniline adsorption with GO-mATP 48 and DMF adsorption with GO and PGO. 30 The greater adsorption efficiency of GO and PGO with catechol might be due to the presence of two hydroxyl groups in catechol, which have higher affinity toward carboxyl groups of GO and PGO.…”

High-efficiency adsorption and regeneration of methylene blue and aniline onto activated carbon from waste edible fungus residue and its possible mechanism

“…Aniline is a weakly basic ionic compound, existing either as neutral or dissociated in aqueous solution. 43 The results in charged when pH below pH pzc . The -COO À on the surface of EFAC is low and the carboxyl groups mainly exist as -COOH.…”

Synthesis and characterization of TiO2/graphene oxide nanocomposites for photoreduction of heavy metal ions in reverse osmosis concentrate

“…14,17,18 In particular, graphene oxide (GO) has drawn much attention as a high potential and efficient material to improve the photocatalytic efficiency of TiO 2 , since its large specic surface area can facilitate the distribution of TiO 2 . 19,20 In addition, GO can serve as an electronic transfer medium, thus reducing the rate of recombination of electron-hole pairs. The charge transfer rate of electrons will be enhanced due to narrow band gap.…”
