“…The rice husk of Youssef et al (2012) went through a complex multiple-step activation course at high temperatures compared to the simple technique at room temperature in this study. Many papers with different rice husk modification conditions for the adsorption of MB also gave the same results as the Langmuir (Sharma et al, 2010;You et al, 2021) and the second-order adsorption model for MB (Ahmad et al, 2020;Chen et al, 2019;Nworie et al, 2019). Namely, Shih (2012) with different BC modifications of HNO 3 , HCl, and H 2 SO 4 and the research of Ahiduzzaman and Sadrul Islam (2016) using ZnCl 2 activation agent for silica rice husk.…”

In this research, rice husk-derived biochar (BC) was evaluated to determine the suitable conditions for the methylene blue (MB) solution adsorption. The characterization of BC was identified by the methods of FT-IR, Raman, and point of zero charges (PZC). The adsorption studies were carried out with BC at different activation conditions (raw BC, HNO3 25% for 4 hours, NaOH 25% for 4 hours, H2O at 90°C for 2 hours and 4 hours, HNO3 25% at 90°C for 2 hours and 4 hours). The activated material then went through an adsorption assessment. Activated BC with NaOH 25% showed its preeminence compared to the other six conditions when reaching the maximum efficiency after the first hour of adsorption. The investigation revealed that the adsorption capacity of the material depends on the activation methods, including pH, activation agent, temperature, and time. The adsorption of BC was consistent with the pseudo-first-order kinetic model and the Langmuir isotherm model, with high correlation coefficients (R2: 0.9838 and 0.9975, respectively). Therefore, it can be concluded that the use of rice husk is feasible for the removal of MB from aqueous solutions.

“…The structures of rice husk, rice straw, dietary fiber from rice bran, and oat straw with and without SE treatment by FTIR spectroscopy were characterized (Ibrahim et al, 2011; Liu et al, 2023; Onyenwoke et al, 2022; You et al, 2021). The results showed that the β‐1,4‐glycosidic bonds of fiber from grain and oil processing by‐products with SE treatment were gradually degraded (Jiang & Guo, 2016).…”

Background and ObjectivesGrain and oil processing by‐products contain dietary fiber with high quality, but most of them have not been utilized due to their high content of insoluble dietary fiber and coarse texture, which are detrimental to the quality improvement of cereal food.FindingsSteam explosion treatment can transfer dietary fiber from insoluble to water‐soluble resulting in a high content of water‐soluble dietary fiber. The content of soluble dietary fiber in cereal processing by‐products with steam explosion treatment is increased from 27.48% to 171% via optimal conditions of steam explosion treatment. The structure of dietary fiber from cereal processing by‐products is disrupted to a honeycomb porous shape, therefore, the physicochemical properties of dietary fiber are improved, such as hydration capacity, oil, cholesterol, and bile salts binding capacity, hypoglycemic capacity, and antioxidant activity.ConclusionsSteam explosion treatment is a rapidly developing and extremely promising pretreatment technology for physicochemical properties enhancement of dietary fiber from grain and oil processing by‐products.Significance and NoveltyThis review can provide some useful references for the properties improvement of soluble dietary fiber in grain and oil processing by‐products by steam explosion pretreatment. It may facilitate the application of soluble dietary fiber in the food industry.

“…It achieved adsorption capacities up to 170 g g −1 for the super-hydrophobic and oleophilic cellulose aerogels. A cellulose-rich modified rice husk was also reported for the removal of MB and Al 3+ ( You et al, 2021 ). It carried out the uptake for MB of 50.15 mg g −1 and the uptake for Al 3+ of 2.87 mg g −1 .…”

In recent years, faced with the improvement of environmental quality problems, cellulose and cellulose-based (nano) composites have attracted great attention as adsorbents. In this review article, we first report the recent progress of modification and functionalization of cellulose adsorbents. In addition, the adsorbents produced by the modification and functionalization of carboxymehyl cellulose are also introduced. Moreover, the cellulose-based (nano) composites as adsorbents are reviewed in detail. Finally, the development prospect of cellulose and cellulose-based (nano) composites is studied in the field of the environment. In this review article, a critical comment is given based on our knowledge. It is believed that these biomass adsorbents will play an increasingly important role in the field of the environment.
