“…The rapid development of textile, printing, food, leather, and paper industries has led to the production of large amounts of dye wastewater, and many substances in dye wastewater absorb sunlight and consume oxygen in water, causing biological hypoxia and affecting the normal growth of aquatic organisms . Dyes are often toxic, teratogenic, and carcinogenic, enriching through the biological chain and eventually entering the human body, causing damage to the immune and nervous systems, interfering with the reproductive and endocrine systems, and increasing the incidence of cancer . Dye removal has become increasingly important from the point of view of human health and environmental protection .…”

To overcome the shortcomings of existing Fenton catalysts, such as secondary contamination caused by iron-containing sludge, harsh pH acidic conditions, poor recovery and recycling performance, and difficult separation, an Fe-loaded geopolymer microsphere (Fe-GLM) with a high specific surface area (68.5 m 2 /g), pore volume (0.0596 cm 3 /g), and excellent Fenton catalytic performance was prepared in this paper for dye wastewater treatment. Degradation experiments for organic dye wastewater show that the degradation ability and morphological structure of Fe-GLM does not change after multiple cycles, achieving a degradation and removal rate of more than 99%. Fe-GLM can be used to degrade both anionic dye and cationic dye wastewater in the pH range of 2−10 showing excellent catalytic performance.

“…The commonly used crosslinking agents for chitosan modi cation and grafting are glutaraldehyde and formaldehyde (Nagireddi et al 2017), related studies have shown that it has side effects on aqueous solutions. Dai et al (Dai et al 2021) used a one-step hydrothermal method to prepare a new type of magnetic lignin adsorbent to remove calcium ions and methylene blue from aqueous solutions, the adsorption capacities is 339.4 mg/g and 281.4 mg/g, respectively. This magnetic adsorbent has a good separation effect, but its adsorption capacity is limited (Ma et al 2018).…”

The problems caused by water pollution are increasingly serious, wastewater contains a lot of heavy metal ions, textile dyes, medicines, etc. However, most adsorption materials usually face problems such as ine cient recycling, high cost, and secondary pollution. As a natural polymer, cellulose has low cost, degradability and good biocompatibility. In this work, by changing the addition amount of sodium hypochlorite during 2,2,6,6-Tetramethylpiperidine-1-oxyl radical (TEMPO) oxidation, nanocellulose with different carboxyl content could be prepared, which is expected to be a good high-e ciency cationic adsorbent due to its rich in hydroxyl groups on the surface and negatively charged. Then the calcium chloride solution was used as the cross-linking agent to prepare nanocellulose beads (TOCNB) by the dropping solidi cation method. As the content of carboxyl groups increases, the Zeta potential value of the nanocellulose dispersion became increasingly negative. The nanocellulose beads all presented a good three-dimensional network porous structure. With the increase of carboxyl group content, the speci c surface area increases from 173 m 2 g − 1 to 367 m 2 g − 1 , and the adsorption capacity for methylene blue (MB) also gradually strengthened. The saturated adsorption capacity of TOCNB on MB was calculated as high as 925.93 mg g − 1 . The nano cellulose bead was a cationic adsorbent with highly e cient adsorption and adjustable speci c surface area, and the preparation method was simple, fast, e cient and green.

A high-performance modified lignin adsorbent was prepared through coprecipitation of ferrous, ferric, and permanganate with lignin in sodium hydroxide solution. The structural characteristics of the synthesized lignin-Fe/Mn binary oxide blend nanocomposite (L-F/M) and its performance on the methylene blue (MB) removal from aqueous solution were evaluated. Influence factors of adsorption effects were analyzed including pH, contact time, dye concentration, temperature, and thermodynamics. The pseudo-second-order kinetic model well described the adsorption kinetics, and the adsorption isotherms best fitted the Langmuir model with a maximum adsorption capacity of 252.05 mg g–1 at 298 K. The adsorption mechanism showed that the L-F/M introduced the metallic element and negative charges to the lignin surface, which improved the adherence of MB via hydrogen bonding, electrostatic interaction, and coordination. Moreover, the removal ratio of MB maintained 81.2% after being used in five adsorption–desorption cycles. Results indicated that the L-F/M obtained was an efficient candidate for dye wastewater treatment.
