“…The ICDW grafted with APTES (ICDW-APTES) exhibited a Q max value of 138.3 mg g −1 (obtained from Liu isotherm model), which is among the highest adsorption capacities of those adsorbents displayed in the literature [19][20][21][22][23][24][25](see Supplementary Table 2).…”

An inorganic sludge from construction and demolition wastes (ICDW) was grafted with APTES to obtain an inorganic-organic modified adsorbent ICDW-APTES. This adsorbent was successfully employed for ciprofloxacin (CFX) adsorption and treatment of synthetic hospital effluent. The chemical composition of ICDW presented large quantities of SiO 2 and Al 2 O 3, which supports its application for being functionalized by APTES that occurred through a chemical reaction between the surface oxygen groups of oxides with the silanol groups of the APTES. The characterization data suggested that APTES was successfully grafted on the ICDW structure. The kinetic studies showed that the general-order provided the best fitness for CFX adsorption on ICDW-APTES. Liu isotherm model presented the best fitness for the equilibrium studies, and it provided a Q max of 138.0 mg g −1 at 40.0°C. Electrostatic interaction was the primary mechanism involved in the adsorption process. The ICDW-APTES also exhibited a good percentage of removal of the two synthetic effluents (71.0 % and 69.0 %).

“…When 1/n ¼ 1, the adsorption process corresponds to linear adsorption, for values <1, it corresponds to chemical adsorption, and values >1 correspond to physical adsorption. 61 These data demonstrate the strong interaction between CNC/CTM and DUR, which shows the potential of CNC/CTM as an effective adsorbent for DUR removal. Table 2 compares the CNC/CTM nanocomposite with other adsorbents reported in the literature.…”

“…The use of biomaterials for adsorption processes instead of conventional materials is now being the subject of interest by many researchers as the commercial value of biomaterials is low, and also they are available in abundance [58]. Naturally-derived biopolymers, which are hyperreactive, chemically stable, possess good physicochemical properties have garnered significant attention that is worth looking into for employing these biopolymers for the role of green adsorbents [59]. Table 1 highlights the major advantages and disadvantages of treatment techniques, available for dye removal from water.…”

Dyes (colorants) are used in many industrial applications, and effluents of several industries contain toxic dyes. Dyes exhibit toxicity to humans, aquatic organisms, and the environment. Therefore, dyes containing wastewater must be properly treated before discharging to the surrounding water bodies. Among several water treatment technologies, adsorption is the most preferred technique to sequester dyes from water bodies. Many studies have reported the removal of dyes from wastewater using biochar produced from different biomass, e.g., algae and plant biomass, forest, and domestic residues, animal waste, sewage sludge, etc. The aim of this review is to provide an overview of the application of biochar as an eco-friendly and economical adsorbent to remove toxic colorants (dyes) from the aqueous environment. This review highlights the routes of biochar production, such as hydrothermal carbonization, pyrolysis, and hydrothermal liquefaction. Biochar as an adsorbent possesses numerous advantages, such as being eco-friendly, low-cost, and easy to use; various precursors are available in abundance to be converted into biochar, it also has recyclability potential and higher adsorption capacity than other conventional adsorbents. From the literature review, it is clear that biochar is a vital candidate for removal of dyes from wastewater with adsorption capacity of above 80%.
