First, a variety of cellulosic waste materials were screened to quantify their adsorptive ability to remove nutrients from water. Due to the low adsorption capacity and frequent leaching of nitrate observed in raw materials, quaternary ammonium functionalization was then employed. Materials were functionalized by adding cationic groups to the biowaste materials to form novel ion exchange adsorbents containing naturally derived biopolymers and/or whole natural fibres with improved nitrate binding capacity. Results revealed that adsorbents originating from high cellulose waste materials can be successfully used to remove nitrate from water. Significant nitrate was removed by functionalized flax and cellulose, of comparable treatment efficiency to a commercial polystyrene-based material used in drinking water filters. Adsorption of nitrate on flax and cellulose based materials was best characterized by the Sips isotherm, reaching maximum sorption capacity of 234.8 and 240.5 mg/g, respectively. This suggests that the interactions between adsorbents and nitrate are more complex than ion exchange alone and can involve other mechanisms, such as dipole/ion force. The kinetics of NO₃^- adsorption was described well by the pseudo-first order model.

Microalgae, as primary producers in the marine food web, play a crucial role in aquatic ecosystems and are inevitably affected by TWP. However, the toxic mechanisms by which TWP influences microalgae's normal physiological activities remain unclear. Given this, <i>Microcystis aeruginosa</i>, a common species in freshwater ecosystems, was selected as an experimental species in this study to investigate the effects of different concentrations of TWP (5, 25, 50, 100 mg/L) on its growth, chlorophyll a content, photosynthetic activity, extracellular polymer secretion (EPS), and oxidative stress. The results showed that TWP had a concentration-dependent inhibitory effect on the growth, chlorophyll content, and photosynthetic activity of <i>Microcystis aeruginosa</i>, with maximum inhibition rates reaching 89.4%, 98.44% and 92.9%, respectively. TWP stimulated the secretion of the EPS of <i>Microcystis aeruginosa</i>, and the secretion of the EPS increased with the increase of the concentration of TWP. TWP also promoted the polysaccharide-to-protein ratio in the EPS with a rise of 27.3–38.5%. Meanwhile, the three-dimensional fluorescence-area-integral analysis indicated that the ratio of the protein-like component was generally higher than the one of the humic-like component in the EPS of <i>Microcystis aeruginosa</i>. The significant increase in superoxide dismutase (SOD) activity under 50 and 100 mg/L TWP exposure predicted a substantial activation of oxidative stress. In contrast, the significant increase in the malondialdehyde (MDA) content indicated the overproduction of reactive oxygen species (ROS) and may lead to lipid peroxidation damage.

A recent focus involves an innovative technology utilizing iron-based catalysts activated by persulfate, renowned for its exceptional PFAS removal efficiency. However, existing literature lacks a thorough comparison of various iron species catalyzing persulfate for PFAS oxidation, with limited analysis of key degradation factors. This paper conducts a comprehensive review, analyzing PFAS degradation efficiency, mechanisms, and pathways using persulfate activated by ferrous ions, zero-valent iron/nano zero-valent iron, iron-based multimetallic catalysts, and various supported iron catalysts. The influence of solution pH and Fe²⁺ concentration on the degradation process is also explored. The review reveals promising PFAS removal performance, often exceeding 90%, by iron-based materials activated with persulfate. Catalysts enhance performance through synergistic elements, optimized structural design, and diverse carriers. Acidic environments favor persulfate activation for organic pollutant degradation, while appropriate Fe²⁺ concentrations enhance removal efficiency, with Fe³⁺ regeneration being the rate-determining step. Iron-based catalyst-activated persulfate follows free radical (SO•- 4, ·OH, O₂^−•) and non-free radical pathways (Fe(IV), ¹O₂, direct electron transfer). Perfluorooctanesulfonic acid (PFOS) degradation involves desulfurization, forming the intermediate product perfluorooctanoic acid (PFOA), followed by defluorination. The critical step is removing one CF₂ unit in each round, leading to complete mineralization.
