“…The thermodynamics parameters, at selected initial nitrobenzene concentrations (100, 200, 300, and 400 mg/L) and temperatures (25,35, and 45 C), are given in Table 7. The negative values of ΔG 0 show the spontaneous adsorption of nitrobenzene onto PAC and ZAC.…”

“…Consequently, a considerable amount of research has focused on the preparation of activated carbon from materials which are relatively abundant and easily available, including different agricultural wastes. [19][20][21][22][23][24][25][26][27] Adsorption mechanism of aromatic contaminants, including nitrobenzene, is still ambiguous. More recently works done by Zhang et al 28 and other researches [29][30][31][32][33][34] have shown that the adsorption capacity of organic compounds is significantly affected by the activated carbon surface chemistry.…”

The present study reports the preparation of chemically activated carbons (PAC and ZAC) from apricot stones using phosphoric acid and zinc chloride, respectively. The potential use of the prepared carbons, as adsorbents, and the effect of chemical activation on the surface properties and adsorptive mechanism of nitrobenzene (NB) were investigated. The physicochemical properties of the obtained materials were characterized by Nitrogen adsorption-desorption isotherms, Scanning Electron Microscope, FTIR Spectroscopy, EDX analysis, Boehm titration, and pH of zero charge. The results show that the prepared samples present high apparent surface areas (1,382 and 1,111 m 2 /g for PAC and ZAC, respectively) and pores volumes with the presence of various functional groups. It was found that pseudo-second model was the most suitable for the fitting of the experimental kinetic data and the intraparticle diffusion was not the unique rate-controlling stage. The adsorption isotherms were well described by the Langmuir and the Freundlich models. According to the Langmuir model, the maximum adsorption capacity of PAC and ZAC were about 476.2 and 490.2 mg/g, respectively. The thermodynamic parameters showed the spontaneity, the exothermic nature, and the decrease in the randomness of the adsorption of nitrobenzene. Chemical regeneration showed that the prepared samples could be used for four time desorption-adsorption cycles with good efficiency for NB removal, indicating that the prepared carbons could be used as a low-cost alternative to commercial activated carbon for the removal of nitrobenzene from wastewater.

Pomegranate peel balls were evaluated as bioadsorbents for removal of Methylene Blue (MB) dye, a model pollutant, from aqueous solutions. Adsorption levels off at 15.8 mg/g and the agrowaste-derived adsorbent can be recycled at least three times. <div>The work conclusively shows that in countries where pomegranate is available, the waste generated by the fruit peel could be considered for future water filtration and environmental protection.</div>

“…The authors also confirmed that the increase of the ionic strength, as well as enhancement of temperature, enhanced the dye sorption capacity of all carbon employed. Daoud et al . manufactured activated carbons from agricultural wastes such as jujube stones and date palm rachis through chemical initiation with an impregnating agent (KOH).…”

A Critical Insight into Biomass Derived Biosorbent for Bioremediation of Dyes

Organic pollutants, such as dyes released during industrial operations are one of the major reasons for the degradation of water quality. However, treatment technologies to remediate these high volumes of wastewaters are often not sufficient. Hence, the excess dye wastewater generated is usually discharged without prior treatment. The use of adsorbents such as activated carbon is widely employed to separate dye molecules from wastewater. Biochar is a popular recent alternative for the treatment of dye‐bearing effluents to selectively isolate dye molecules. Biochar is normally manufactured in the oxygen free environment by thermal degradation of organic materials. On the other hand, dyes are extensively employed in many textile industries because of their desirable properties including attractive colour, water‐fast and easy application methods. Nevertheless, during the dyeing process of cellulose fibres around half of the applied dyes may enter the wash water, and these let outs are highly resistant to traditional wastewater treatment methods. Henceforth, new techniques need to be applied for successful remediation of dye wastewaters. In this perspective, an endeavor has been made in this work to explore the possibility and practicability of biochar as sorbent material for dyes.
