“…Activated carbon can be obtained from different precursors such as rosemary waste, olive tree waste, coconut coir, pomegranate peel, tapioca peel, olive pomace, cassava slag, bamboo shell, walnut shell, paper waste, and sugarcane bagasse in Rhodamine B removal studies (Albanio et al 2021;Boukerzaza et al 2021;Ghibate et al 2021;Hou et al 2019;Naboulsi et al 2023;Nascimento et al 2021;Vigneshwaran et al 2021;Wu et al 2020). Exhibiting a high carbon content, porous structure and functional groups makes agriculture wastes are commonly preferable to prepare activated carbon and utilize in the adsorption of dyes (Dai et al 2018).…”

In this study, the adsorption performances of ZnCl2, KOH and H3PO4 impregnated activated carbons derived from olive stones in the removal of Rhodamine B dye from aqueous solution were investigated. The equilibrium time was determined to be 6 hours, and the highest adsorption capacity was achieved by ZnCl2 impregnation (190.67 mg g-1) followed by KOH (118.26 mg g-1), H3PO4 (49.81 mg g-1), and crude olive stones (21.57 mg g-1) compared to the commercial powdered activated carbon (254.30 mg g-1). While different pH values (2-10) did not exhibit much effect, pH 4 was the most efficient one. The sorption capacity reached equilibrium at 200 mg L-1 of initial dye concentration. 0.01 gram of ZOSAC had 39% removal performance, whereas 0.05 gram was found to be sufficient for 100% removal. The presence of background ions enhanced the adsorption of Rhodamine B. Pseudo-second order model (R2=0.99) was most suitable for the experimental data among kinetic models. Redlich-Peterson (R2>0.98) model was found to be most suitable equilibrium model for all ACs. The temperature increase from 30 to 50℃ had an increasing effect on the adsorption capacity. It was also revealed that the adsorption was endothermic (∆H°=14.91 kJ mol-1) and thermodynamically favorable (∆G°<0) for ZOSAC. At the end of the fifth adsorption/desorption cycle, the removal efficiency was 94% and optimum adsorption conditions were determined as 45 ℃ and 252 mg L-1. As a result, ZOSAC was found to be the most efficient and reusable impregnated olive stone derived activated carbon in the Rhodamine B removal.

“…Among the most common dyes are rhodamine B (RhB) and methylene blue (MB). A cationic dye, RhB has been identi ed as a Grade 3 carcinogen by the International Agency for Research on Cancer (IARC) due to its toxicity and potential carcinogenic mutagenicity (Hossain and Alam 2012; Al Ashik et al 2023;Naboulsi et al 2023). On the other hand, despite not exhibiting high toxicity and even being occasionally used as medicine, the presence of MB in water can still have harmful effects on living organisms as it does not degrade easily (Zhang et al 2016;Birniwa et al 2022).…”

Among the most common water contaminants, dyes are responsible for polluting rivers and other water bodies as well as contributing to other environmental problems, thus posing serious health hazards to humans and animals. In order to minimize these environmental impacts, this study proposes the use of Onecarpus bacaba Mart fiber residues, in natura (OBMi) and NaOH-modified (OBMm), to bioadsorb rhodamine b (RhB) and methylene blue (MB) dyes. The biosorbents OBMi and OBMm were characterized by means of infrared spectroscopy, thermogravimetric analysis, X-ray diffraction, Boehm titration, PZC, and scanning electron microscopy. This study also analyzed the influence of pH, contact time, absorbent mass, temperature, and contaminant concentrations by means of batch equilibrium assays. Maximum OBMm adsorption capacity for RhB and MB at 25°C was 26.60 mg g− 1 and 407.98 mg g− 1, respectively. In both systems, OBMm:RhB and OBMm:MB, adsorption kinetics followed a pseudo-second-order law, and the Langmuir and Freundlich models constituted the best fit for isothermal curves. Lastly, thermodynamic parameters indicated that adsorption of both RhB and MB onto OBMm is spontaneous.
