“…As it is well known that the adsorption efficiency depends on the physical and chemical properties of the adsorbent and dye, as well as the adsorption conditions such as time, temperature, dye and adsorbents concentration, etc. [ 62 ], the optimization of these parameters has been carried out to best accomplish the removal of MB by the SA-LNP beads.…”

A novel and effective green system consisting of deep eutectic solvent (DES) was proposed to prepare lignin nanoparticles (LNPs) without any lignin modification. The LNPs are obtained through the dialysis of the kraft lignin-DES solution. The particle size distribution, Zeta potential and morphology of the LNPs are characterized by using dynamic light scattering (DLS), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The average diameter of LNPs is in the range 123.6 to 140.7 nm, and the LNPs show good stability and dispersibility in water. The composite beads composed of LNPs and sodium alginate (SA) are highly efficient (97.1%) at removing methylene blue (MB) from the aqueous solution compared to 82.9% and 77.4% by the SA/bulk kraft lignin composite and pure SA, respectively. Overall, the LNPs-SA bio-nanocomposite with high adsorption capacity (258.5 mg/g) could be useful in improving water quality and other related applications.

“…The time-dependent adsorptive processes of CR were analyzed by applying the pseudo-first-order equation, 26,37,40 second-order equation, 40,41 and intra-particle diffusion models 41 as follows:ln( Q e − Q t ) = ln Q e − k 1 t where each variable is defined as follows: Q e and Q t (mg g −1 ) denote the amount of dye adsorbed at equilibrium and time t , k 1 (min −1 ) denotes the pseudo-first-order rate constant, k 2 (g mg −1 min −1 )) denotes the pseudo-second-order rate constant, k id (mg g −1 min −0.5 ) denotes the intra-particle diffusion rate constant, and C i , r ( r = 1,2,3) denotes the intercept related to the boundary layer effect.…”

Conventional pulping processes, such as soda, soda‐Antraquinone (AQ), and kraft, are currently used for non‐wood pulping. The main challenges of non‐wood pulping in conventional pulping processes are (1) large amounts of silica cause silica‐related operational difficulties in the process; (2) large amounts of fines/parenchyma cells decrease the drainage; and (3) the bulky nature of raw materials increases the collection/transportation cost, hampering large‐scale commercial operations. Alternative pulping processes are therefore being developed. This paper reviews the current status of alternative non‐wood pulping processes and their integration with the biorefinery concept. Several promising methods have been investigated at the laboratory or pilot scale. Organic acid and potassium hydroxide pulping processes are attractive alternatives for non‐wood pulping. Dissolved lignin and hemicelluloses in spent liquor can lead to the production of valuable co‐products, fitting well with the integrated biorefinery concept. Non‐wood biomass can be important raw material for pulping in forest‐deficient countries. © 2020 Society of Chemical Industry and John Wiley & Sons, Ltd
