“…In general, the adsorption energy is 1 to 8 kJ/mol for physical adsorption and 20 to 40 kJ/mol for chemical adsorption [30]. In this study, the adsorption energy of MB was found to be 3.352 kJ/mol Rattan sawdust 294.14 [31] Waste apricot 102.0 [9] Palm kernel fiber 95.4 [25] Sunflower oil cake 16.4 [9] White pine sawdust 102 [28] Rice straw 40.02 [32] Garlic peel 142.86 [27] Tea waste 85.16 [33] Banana peel 20.80 [16] Orange Peel 18.60 [1] Rice husk 40.59 [19] Peanut hull 68.03 [8] ( Table 2). Therefore, the adsorption process of MB by corncob is more influenced by physical adsorption.…”

Using the abandoned agricultural by-product corncobs, the most commonly used methylene blue (MB) dyestuffs were removed. This experiment is very meaningful because it is the recycling of resources and the use of environmentally friendly adsorbents. According to the Hauser ratio and porosity analysis, the corncob has a good flow ability of the adsorbent material and many pores, which is very advantageous for MB adsorption. As a result of the experiment, MB concentration of less than 0.005 g/L was very efficiently removed with 10 g/L of bioadsorbent corncob and the maximum adsorption capacity of corncob for MB dyes was obtained at 417.1 mg/g. In addition, adsorption process of MB onto corncob was a physical process according to adsorption energy analysis. Corncob can efficiently and environmentally remove MB in aqueous solution, and is very cost effective and can recycle the abandoned resources.

“…As the pH increases, the surface of the biomass acquires a negative charge and a deprotonation of the surface is carried out which facilitates the adsorption of MB and therefore the capacity of adsorption of this pollutant by the biomass increases [37]. is is mainly because in the solution, the MB is positively charged; hence, its adsorption is more effective when the surface charge presents a negative value [44,45]. erefore, it was considered that a pH value of 10 was appropriate for carrying out the kinetic experiments.…”

Currently, there is a great pollution of water by the dyes; due to this, several studies have been carried out to remove these compounds. However, the total elimination of these pollutants from the aquatic effluents has represented a great challenge for the scientific community, for which it is necessary to carry out investigations that allow the purification of water. In this work, we studied the bioadsorption of methylene blue on the surface of the biomass obtained from the algae D. antarctica. This material was characterized by SEM and FTIR. To the data obtained in the biosorption experiments, different models of biosorption and kinetics were applied, finding that the best fit to the obtained data is given by applying the pseudo-second-order models and the Toth model, respectively. It was also determined that the maximum adsorption capacity of MB on the surface of the biomass is 702.9 mg/g, which shows that this material has great properties as a bioadsorbent.

“…FTIR analysis showed the hydrolysis of lignin‐carbohydrates linkages and lignin deacetylation . Zhang et al . suggested that a strong absorption peak at 1376 cm −1 is representing the cleavage of β–O–4 and α–O–4 linkages and accumulation of non‐etherified phenolic OH groups in lignin after organosolv (Table ).…”

SEM analysis of organosolv pre-treated rice straw showed separated, exposed, ruptured fi ber structure with reduced outer bristles (2 to 3 μm) and pores in comparison to rigid, ordered, and smooth structure of native rice straw with 7 to 19 μm outer bristles.…”

The surplus availability of rice straw, its limited usage, and environmental pollution caused by its ineffi cient burning has fostered research for its valorization to biofuels. This review elucidates the current status of rice straw potential around the globe along with recent advances in revealing the critical factors responsible for its recalcitrance and chemical properties. The role and accumulation of high silica content in rice straw has been elucidated with its impact on enzymatic hydrolysis in a biorefi nery environment. The correlation of different pre-treatment approaches in modifying the physiochemical properties of rice straw and improving the enzymatic accessibility has also been discussed. This study highlights new challenges, resolutions, and opportunities for rice straw based biorefi neries.
