“…So far, numerous techniques including catalytic degradation, membrane separation, adsorption, oxidation and occulation have been utilized in the region of wastewater treatment. [4][5][6][7][8] Adsorption stands out as the most promising technique based on its great efficiency, simplicity and inexpensiveness. 9,10 However, some efficient adsorbents, such as activated carbon, resin and bentonite, restricted by the high manufacturing cost or complicated processes are difficult to be applied in massive wastewater treatment.…”

“…Sugarcane bagasse, which is composed of macromolecules, is a residue from the sugarcane crushing process. These macromolecules have hydroxyl groups which react chemically to form an active adsorbent material with accepted properties [20]. The usage of bagasse as adsorbent material to remove different pollution was illustrated in the literature [21].…”

Adsorbent materials for industrial and environmental applications are the goal of seeking research under active investigation now. Activated carbons could be obtained from the organic material after been chemically or physically treated. In Egypt, Sugarcane bagasse could be considered one of the agricultural wastes that frequently produced. In this study, the low-cost adsorbent was prepared from raw Bagasse. The batch experiment was set up to determine the effect of using the agriculture waste (sugarcane bagasse) without any modification and activated it chemically and physically on methylene blue removal. The influence of adsorbent amount, agitation rate, and temperature on the dye removal were studied. The result shows that the percentage of dye removal reached up to %99.6 when the initial dye concentration was 15 ppm, and the amount of sorbent (chemically activated) was 0.3 g at room temperature. The adsorption kinetics and isotherms for the removal of methylene blue were represented with different models. It was detected that Langmuir and Freundlich's equations have the R 2 value closed to unity, and the maximum adsorption calculated capacity was 2.2 mg/g when the initial dye concentration was 15 ppm. Furthermore, pseudo-first-order and pseudo-second-order were fitted to examine the adsorption kinetic, and a pseudo-secondorder calculated the highest adsorption rate for the raw bagasse (0.59446 g/mg.min).

“…The highest removal efficiency was calculated as 75.85% and 98.14% for natural and biochar prina, respectively. Biochar qe Natural qe Wang et al (2020), in their removal study with active sugarcane adsorbent against the initial CV concentration, achieved a partially decreasing removal efficiency with increasing initial concentration. They also stated that similar to this study, the adsorption capacity (qe) increased rapidly from the 200 mg/L concentration to the 1000 mg/L concentration.…”

“…Similar to this study, in the adsorbent dosage versus removal efficiency experiments, they obtained a constantly increasing removal efficiency despite the increasing adsorbent dosage. Wang et al (2020) carried out CV removal studies with activated sugarcane adsorbent. The adsorbent dosage versus removal efficiency study obtained 90% removal efficiency at the adsorbent dosage of 3.33 g/L and the removal efficiency remained constant at increasing adsorbent dosages.…”

In this study, as industrial waste, prina was used as an adsorbent substance with its natural and thermally modified form. The prina used in the study was taken as waste material from an olive oil factory in Ayvalık, Turkey. In this study, the removal possibilities of the toxic effect of crystal violet dye found in various industrial wastewaters with prina adsorbent were investigated. By using the pyrolysis method at 600 °C, the biochar form of prina was obtained. Natural and biochar prina and crystal violet (CV) dye have been tried under different adsorption conditions. For this purpose, experiments were carried out at different prina dosages, initial dye concentrations and contact times. The highest removal efficiencies are around 75% in natural prina, while the biochar is around 99% in prina. Also, concentration studies were applied to Langmuir and Freundlich adsorption isotherm models. As a result of the isotherm study, it was seen that the adsorption mechanism was suitable for Freundlich isotherm model. The contact time removal studies were applied to pseudo-firstorder, pseudo-second-order and intraparticle diffusion kinetic models, and adsorption was found to be fit with the pseudo-second-order kinetic model. According to the experiment results, it was observed that the thermal treatment caused a significant increase in the removal efficiency. It was found that it is an efficient adsorbent material that can be used to remove the CV dye from the aqueous solutions.
