“…The second linear range shows a gradual adsorption process controlled by intraparticle diffusion, which is related to pore diffusion and features faster transfer to phenol. − The third linear range is the final equilibrium phase, in which intraparticle diffusion begins to stabilize, probably due to the low solute concentration in the solution, which is related to surface diffusion according to Abdelwahab and Amin and Andrade et al The increase in the constant C values from 0.339 to 13.544 mg·L –1 for phenol and from 0.455 to 38.093 mg·L –1 for Cd 2+ demonstrates the increase in the boundary layer in the region and consequently greater diffusion resistance. In addition, the increase in the constant C may indicate an increase in the boundary density, favoring the internal mass transfer and the reduction of the external mass transfer …”

In this work, the competitive adsorption of phenol and cadmium using the biochar of peanut shell (BPS) as an adsorbent was evaluated. The biochar was characterized as mesoporous and amorphous, with carbonyl and carboxyl groups, and pHPZC 7.9. The system reached equilibrium in around 180 min. For the single-component equilibrium, the Langmuir–Freundlich model was the one that best represented the data with a maximum adsorption capacity of 16.32 mg·g–1 for phenol and 34.73 mg·g–1 for cadmium. For the binary mixture, the extended Freundlich and modified Redlich–Peterson models were the ones that presented the best adjustments, indicating the heterogeneity of the adsorption process. The results demonstrated the synergy of Cd2+ ions in phenol adsorption. The biochar presented potential for the removal of organic and inorganic substances simultaneously. The adsorption mechanism showed a limiting step on the surface of the BPS and greater access of Cd2+ to the adsorptive pores.

“…In this case, design of an adsorbent with needed properties is very essential. Many adsorbents (Li et al , 2021a; Nugraha et al , 2021; Shanmugam et al , 2021; Zhang et al , 2021) have been synthesized and used to effectively remove organic dyes and showed excellent properties.…”

Purpose The purpose of this study was to prepare carboxylated attapulgite (APT-COOH) and then be used as one of the ligands to prepare metal organic framework (MOF) hybrid materials to reduce the cost of MOF materials and improve the dispersed condition of APT. And then the materials were used to enrich anionic dye Congo red from aqueous solution. Design/methodology/approach The MOF hybrid materials were designed by means of facile reflux method rather than hydrothermal method, characterized by Thermogravimetric Analysis (TGA), Fourier Transform Infrared (FTIR) Spectrometer and pore structure. The dispersed degree of APT-COOH in the MOF materials was validated according to adsorption efficiency for Congo red. Findings Due to introduction of APT-COOH, the microenvironment of the MOF materials changed, leading to different adsorption behaviors. Compared to the MOF material without APT-COOH, the adsorption capacities of the hybridized MOF materials with different amounts of APT-COOH introduced increased by 4.58% and 15.55%, respectively, as the initial concentration of Congo red solution of 300 mg/L. Meantime, hybridized MOF materials were suitable to remove Congo red with low concentration, while the MOF material without APT-COOH was appropriate to enrich Congo red with high concentration. Research limitations/implications The microstructure of MOF hybrid materials in detail is the further and future investigation. Practical implications This study will provide a method to reduce the cost of MOF materials and a theoretical support to treat anionic dyes from aqueous solution. Originality/value APT-COOH was prepared and used as one of the ligands to synthesize MOF material to improve the dispersed degree of APT-COOH and reduce the cost of the MOF materials. The adsorption efficiency was greatly enhanced with low concentration of Congo red solution, and the results indicated that hydrogen bonding, electrostatic interaction, and p-p conjugation were involved in the adsorption process. The prepared MOFs materials exhibited excellent adsorption efficiency, which made the present materials highly promising and potentially useful in practical application as adsorbents to enrich anionic dyes such as Congo red from aqueous solution.
