Removal of methylene blue from aqueous solutions using phosphoric acid activated carbon produced from hazelnut husks

Performance, kinetics, and equilibrium of methylene blue adsorption on biochar derived from eucalyptus saw dust modified with citric, tartaric, and acetic acids

“…The perfect fit of the experimental data with the Langmuir isotherm model indicated that the adsorption behavior was predominantly monolayer adsorption, which involves chemical and physical adsorption. This observation is consistent with previous reports on MB adsorption on activated carbon prepared from hazelnut husks (Ozer et al, 2012) and rattan sawdust (Hameed et al, 2007).…”

Adsorption of Eriochrome Black T (EBT) dye using activated carbon prepared from waste rice hulls—Optimization, isotherm and kinetic studies

“…Thus, research on the production of activated carbon from a renewable, low-cost indigenous agricultural waste has gained attention worldwide because of its low cost and highly abundant characteristics [21][22][23]. Some of the agricultural wastes that have been studied as possible source of activated carbon are wood [24], bagasse [25], coir pith [26], orange peel [27], bamboo dust [28], corncobs [29], cassava peel [30], eucalyptus bark [31], palm shell [32], coconut shell [33], tobacco stem [34], hazel nut [35,36] and some other biomass resources.…”

Adsorption of Cd(II) Ions onto Activated Carbon Prepared from Hazelnut Husks

“…[21] But, HS has not been used for any purpose by the hazelnut producer and generally disposed by incineration in threshing field resulting of air pollution. [23][24][25] Hence, preparation of AC from HS is important. Also a few studies have been reported in the literature.…”

“…[23] AC from HS produced phosphoric acid was used for the removal of methylene blue from aqueous solutions. [24] According to our literature survey, this is first study about the adsorption Cd(II) ions on the activated carbon prepared from hazelnut husk using phosphoric acid activation method.…”

“…Also a few studies have been reported in the literature. [23][24][25] Ni(II) adsorption was investigated onto carbonaceous material prepared from HS by treating with sulfuric acid. [25] Adsorption of lead (II) and copper (II) ions onto AC prepared from HS with ZnCl 2 was investigated by Imamoglu and Tekir.…”
