1.In addition, the impacts of different initial pH values, co-existing inorganic ions and various
adsorbent dosages on CTC adsorption removal by the JLUE-MOGs were explored. CTC solutions with increasing concentrations from 20 to 600 mg⋅L–1 were used for the adsorption isotherms at 25.0 ◦C.
2.Additionally, it is well known that diffusion is the key in the adsorption procedure, which can be divided into three steps: external-surface adsorption, intra-particle diffusion and adsorption equilibrium .
3.Furthermore, C is the parameter which has positive correlation with the thickness of diffusion boundary layer. In this study, the value of C increased with the enhanced initial
CTC concentrations, which implied that the internal mass transfer was more prone to be influenced than the external mass transfer with the CTC concentration.
4.The pH values of the solutions give a certain impact on the surface charge properties of the adsorbent and the forms of the adsorbate.
5.The exposed numbers of available active sites increased with larger BET, and the mass transfer was strengthened by hierarchical pore structures, thereby enhancing the adsorption capacity of the adsorbents.
6.The resultant lignocellulose-based nanocomposite aerogel possessing a high specific surface area (95.3 m2/g), surface charge density (1.78 mmol/g) and well-preserved lignocellulosic structure, strongly adsorbed TC with a maximum adsorption capacity of 70 mg/g via a combination of inter-molecular interactions (i.e., hydrogen bonding and π-π stacking) and electrostatic forces.
7.Multiple strategies have been proposed for TC removal including adsorption-enrichment , advanced oxidation , biodegradation , electro-chemical degradation and photocatalytic oxidation . Among them, the combination of adsorption and photocatalysis is especially attractive owing to its high efficiency, tunability and adaptability in TC removal from wastewater.
8.However, the mechanical liberation of nanofibrils from lignocellulose is a cumbersome process due to the recalcitrant nature of cellulose- hemicellulose-lignin-complex. In this
regard, various chemical pretreatments have been developed to improve the disintegration of natural lignocellulose into its nanoscale constitu-ents . Deep eutectic solvents (DES)
have emerged as alternatives to conventional organic solvents for lignocellulose processing due to their favorable physicochemical properties such as negligible vapor pressure, recyclability and non-toxic character .
9.There is benign compatibility between TiO2 and lignocellulose and hydrogen bonding
interactions exist between the abundant hydroxyl groups in lignocellulose and Ti––O bonds in TiO2 . Undoubtedly, the combination of lignocellulose and TiO2 has great potential for the efficient removal of organic contaminants via coupling adsorption and photocatalytic degradation processes.
10.The DES is expected to facilitate the release of nanofibrils from bagasse fibers by introducing ionic functional groups and simultaneously weakening the hydrogen bonding interactions between the lignocellulosic components (i.e., cellulose, hemicellulose and lignin). DES有望通过引入离子官能团并同时削弱木质纤维素组分（即纤维素、半纤维素和木质素）之间的氢键相互作用，促进甘蔗渣纤维中纳米纤维的释放。
