“…However, dye adsorption is a cumulative result of all direct and interaction effects of independent variables. Response surface methodology (RSM) offers various statistical designs for studying the direct and interaction effects among the independent variables involved in adsorption with the advantages like less experimental samples, less input time, and overall reducing the experimental costs (Akbar et al 2018;Bhomick et al 2020;Danish et al 2018;Ghosh et al 2019;Hannachi and Hafidh 2020).

“…1 Ab, 1B, and 1 Cb). The reason for could be explained as with the increase in initial dye concentration, mass transfer of dye molecules from solution to the solid phase (i.e., onto JSAC surface) became easier as high dye concentrations resulted in lowering of mass transfer resistance coupled with the more driving force for transfer of dyes from solution to a solid surface (Bhomick et al 2020;O'Mahony et al 2002;Saeed et al 2015).…”

In this study, jute stick derived activated carbon (JSAC) has been evaluated as an adsorbent to remove textile dyes namely acid red-1 (AR-1), reactive orange-16 (RO-16), and methylene blue (MB) from water using the Box-Behnken model of response surface methodology (RSM). The direct and interaction effects of four independent process parameters namely solution pH, initial dye concentration, adsorbent dose, and time were investigated and optimized for textile dye by using ANOVA. The optimum conditions for maximum % dye removal were found to be pH-3, initial dye concentration-500 mg L −1 , adsorbent dose-0.9 gL −1 , and time-110 min for AR-1; pH-3, initial dye concentration-350 mg L −1 , adsorbent dose-1.5 g L −1 , and time-110 min for RO-16, and pH-11, initial dye concentration-415 mg L −1 , adsorbent dose-0.7 g L −1 , and time-86 min for MB, respectively. Adsorption equilibrium investigations were carried out with Langmuir, Freundlich, and Jovanovic models. Based on error analysis, Langmuir isotherm was found the best-fitted model with maximum adsorption capacities of 588.2, 156.3, and 384.6 mg g −1 for AR-1, RO-16, and MB, respectively. The dimensionless factor, R L values (range: 0.0152-0.2665) also indicated spontaneous and favorable adsorption of studied dyes onto JSAC. Dye loaded adsorbents were easily regenerated with 0.1 M HCl (for MB) and 0.1 M NaOH (for AR-1/RO-16) and reused up to the 4th cycle. The present investigation indicated that JSAC, with a highly porous and stable structure coupled with various functional groups, holds immense potential as a new adsorbent for textile dyes.

“…Second, adhesion can be through many mechanisms, not necessarily chemical bonds, but strong and weak. The adsorption mechanisms of dyestuffs can be not only through electrostatic interactions as in metal ions, but also through strong π-π dispersion interactions between the aromatic rings of the dye molecules and the graphene layers of the adsorbent, and non-electrostatic partial H-bonds [48].…”

N atural waters are getting more and more polluted due to the activities of many industry organizations such as juice, coffee, and cereal processing plants. The contamination of the water used for drinking and other purposes by partially treated or untreated discharges from chemical industries, petrochemical industries, oil refineries, oil spills, rolling steel mills, unrefined domestic sludge, and pesticide runoff threaten both human health and environmental health [1]. Dyestuffs, one of many different types of contaminants, are among the chemicals that pose this threat. Synthetic dyestuffs are widely used worldwide in textile staining processes. Synthetic dyestuff classes are the azo type, including reactive, disperse, and acid dyes. Azo dyes account for 65% of the total dye production in the world [2]. Today, biological treatment is the most widely used method to decompose dye waste. However, this process is not very successful in removing dyes effectively. For this reason, dyes

With the development of economy and increasing environmental awareness, how to effectively remove organic pollutants in wastewater is a research hotspot. Adsorption is one of the effective methods, and the adsorption material is the key factor to determine the efficiency. In this review, biomass‐derived carbon materials as adsorbents of organic pollutants and the adsorption mechanism are discussed in depth. The effects of carbonization and activation on the morphology and structure of carbon materials; the modification strategies of carbon adsorbents, the adsorption performance of biomass‐derived carbon materials for organic pollutants are described and illustrated; the future work of the biomass‐derived carbon materials is proposed.
