“…The study of the effect of pH on the removal of cationic and anionic dyes confirms the results of previous researchers (Albadarin et al, 2011;Ramesh et al, 2005;Kyzas et al, 2012;Lafi and Hafiane, 2015;Lafi et al, 2014). MB was removed from the solution more efficiently at high pH as the adsorption mechanisms associated with the formation of a complex between the positively charged ions and negatively charged dye ion on the adsorbent surface.…”

“…MB was removed from the solution more efficiently at high pH as the adsorption mechanisms associated with the formation of a complex between the positively charged ions and negatively charged dye ion on the adsorbent surface. While the adsorption capacity of OR increases in basic medium by electrostatic interaction between negatively charged dye ions and positively charged cell of co-granules surface (Lafi and Hafiane, 2015).…”

“…Coffee wastes are mostly used as a source for bio-energy and fertilizers (Cruz et al, 2015;Adi and Noor, 2009). In some research papers, coffee waste has been used as biosorbents for the removal of acid dye (Gupta and Suhas, 2009;Rafatullah et al, 2010;Lafi et al, 2014;Roh et al, 2012;Kyzas et al, 2012), organics (Al-Zaben and Mekhamer, 2013;Lafi and Hafiane, 2015;Rossmann et al, 2012) and metal ions from aqueous solutions (Azouaou et al, 2010;Boonamnuayvitaya et al, 2004;Ching et al, 2011;Kaikake et al, 2007;Oliveira et al, 2008;Pujol et al, 2013). Coffee waste has a high C/N ratio, and contains carboxylic group (Cruz et al, 2015) ensuring high efficiency for metal ions removal due to chelates formation (Adi and Noor, 2009;Lafi et al, 2014).…”

Limestone and coffee waste were used during the wet co-granulation process for the production of efficient adsorbents to be used in the removal of anionic and cationic dyes. The adsorbents were characterized using different analytical techniques such as XRD, SEM, FTIR, organic elemental analysis, the nitrogen adsorption method, with wettability, strength and adsorption tests. The adsorption capacity of granules was determined by removal of methylene blue (MB) and orange II (OR) from single and mixed solutions. In the mixed solution, co-granules removed 100% of MB and 85% of OR. The equilibria were established after 6 and 480 h for MB and OR, respectively.

“…The stretching mode of the structural hydroxyl groups was correlated with the moderate intensity bands at 3740 and 3664 cm −1 [58,15], while the band at 3419 cm −1 was assigned to both nitrogen-bearing (NH 2 ) group of the accompanying organic matters [45,70] and to the stretching mode of water molecules [82]. Also the presence of the 2860 and 2925 cm −1 feeble bands is correlated with symmetric and asymmetric stretching vibration of C-H groups, correspondingly [16,69,42]. These C-H groups were also ascribed to the organic content of the TGSH.…”

Talc-graphite schist (TGSH) is a natural organo-mineral complex that was derived from the regional metamorphism of organic matter-bearing calcareous clays under the lowest temperature and pressure of the green schist facies (573-632 K and 1-3 Kbars, respectively). The application of TGSH that is widely available in the Meatiq area (Eastern Desert, Egypt) was investigated for the first time ever in the remediation of methylene blue dye (MB) from aqueous solutions. The characterization of the TGSH was carried out using various techniques (XRF, XRD, SEM, FT-IR and BET surface area), and its MB removal capacity was estimated at different experimental conditions. The MB adsorption by TGSH was time-and pH-dependent process, where 120 min was sufficient enough to attain equilibrium. The MB adsorption capacity by the TGSH was directly proportional to the applied temperature, confirming that the MB adsorption process was endothermic in behavior. Based on the determination coefficients, the pseudo-second-order equation (R 2 = 0.939) explained MB adsorption data better than the first-order one (R 2 = 0.653). Meanwhile, intra-particle diffusion was not the sole controlling rate in MB removal by the TGSH. Moreover, the nonlinear regressions of Langmuir model (R 2 = 0.876) explained the equilibrium data better than the other applied models (Temkin, R 2 = 0.793, and Freundlich, R 2 = 0.752). On the other hand, the estimated q max (maximum removal capacity) of Langmuir was 9.41 mg/g at ambient temperature. Hydrogen bonding and electrostatic interaction were the governing mechanisms of MB removal by TGSH with variable impact in accordance with the prevailing pH condition.

“…Spontaneity, feasibility and endothermic nature of adsorption process were shown by the calculation of thermodynamic parameters and adsorbent was regenerated using 0.1M NaOH. The adsorption of dyes onto the adsorbent surface was possibly due to the interactions between dye molecules and functional group on the surface of adsorbent [35]. Activated carbon prepared from date stones by activation with nitric acid was evaluated for their capacity to uptake methyl orange and Maxilon blue from aqueous solutions.…”

Dyes are the chemical substances which impart color upon the application to the substrate by mechanical retention, physical adsorption, covalent bond formation and complexation with salts. Different approaches for dye removal include chemical approach (electrochemical destruction, ozonation, and Fenton-like oxidation), physical approach (filtration, coagulation, adsorption and ion-exchange) and biological approach (aerobic and anaerobic oxidation, microbial cultures). However, adsorption onto low cost bioadsorbents derived from agricultural wastes in beneficial over other techniques due to sludge free procedure, recovery of adsorbent, more efficient, technically easy and non-polluting characteristics. Agricultural wastes are chemically modified using alkali, acids, oxidizing agents, surfactants; and are modified by physical activation and biological treatments to alter its pore size, physic-chemical properties, chemical composition and surface area to enhance its adsorption potential. This review focuses on various adsorbents derived from agricultural wastes as such and in its chemically modified form for the uptake of dyes from aqueous solution, different factors affecting the uptake of dyes from aqueous solution and thermodynamic parameters for the adsorption process. Mechanism for the dye removal and different adsorption isotherms applicable to its are also presented.
