“…The decrease in humic substances with the addition of zeolite could also be attributed to their electrostatic interaction with the positively charged ions adsorbed on the natural zeolite. Islam et al (2020) reported that the presence of small ions, such as phosphate and bicarbonate, significantly reduced HA adsorption while the presence of either Ca 2+ or Mg 2+ enhanced their adsorption. However, being the pore size in zeolite relatively small, humic and fulvic acids are generally adsorbed only on the exterior surface, while metal ions and small anions can penetrate into the microporous structures (Islam et al, 2020).…”

Sustained tillage and continual applications of phytopharmaceutical and fertilizers using heavy machineries frequently give rise to soil erosion, loss of soil organic matter (SOM) and contamination phenomena in Mediterranean vineyards. Because of their distinctive properties, applying natural zeolites to vineyard soils can conceivably affect the efficient use of fertilizers and reduce nutrient leaching losses. This work assesses the impact of zeolite amendment at differing rates (0, 5 and 10 t/ha) on the chemical and biochemical soil properties of three vineyard soils after 6 months from initial treatments. In particular, chemical properties usually related to soil fertility were evaluated along with more sensitive indicators of soil functionality and indicators of chemical-structural characteristics of SOM. The vineyard soils amended with zeolite showed higher nutrient availability and dehydrogenase activity if compared with the control soils. In addition, even though total organic carbon (TOC) content was unchanged, a decrease in humic substances was observed in the zeolite-treated soils. These results suggested that the stimulation of soil microbial processes by adding zeolite triggered a microbial mineralization process of soil organic carbon stocks. In addition, the modification in the chemical-structural composition of soil organic matter in zeolite-treated soils was shown by the pyrolysis-gas chromatography (Py-GC) results. Py-CG of soil organic matter clearly demonstrated an increase in the labile aliphatic compound furfural and a decline in the more stable aromatic pyrolytic fragments in zeolite-treated soils in contrast with the control soils, thus indicating the higher extent of decomposition of the SOM more stable pool.

“…They are a complex mixture of organic materials including viruses, bacteria, polysaccharides, proteins and humic elements (such as fulvic acids and humic acids). Water with these substances may become yellow-brownish, odorous and have foul taste, which makes water undrinkable [16]. Meanwhile, NOM could cause a number of technical issues in water treatment [17], such as membrane fouling and the formation of dihaloacetonitrile (toxic to human health) during chlorination processes.…”

Advances in Circular Bioeconomy Technologies: From Agricultural Wastewater to Value-Added Resources

et al. 2021

View full text Add to dashboard Cite

This review systematically outlines the recent advances in the application of circular bioeconomy technologies for converting agricultural wastewater to value-added resources. The properties and applications of the value-added products from agricultural wastewater are first summarized. Various types of agricultural wastewater, such as piggery wastewater and digestate from anaerobic digestion, are focused on. Next, different types of circular technologies for recovery of humic substances (e.g., humin, humic acids and fulvic acids) and nutrients (e.g., nitrogen and phosphorus) from agricultural wastewater are reviewed and discussed. Advanced technologies, such as chemical precipitation, membrane separation and electrokinetic separation, are evaluated. The environmental benefits of the circular technologies compared to conventional wastewater treatment processes are also addressed. Lastly, the perspectives and prospects of the circular technologies for agricultural wastewater are provided.

“…Examples, advantages, and disadvantages of the various adsorbents are a topic of multiple reviews. 57 , 62 , 63 Those adsorbents can be categorized in the following groups: carbonaceous, mineral, and polymeric materials and (nano)composites and nanomaterials (nanoparticles and nanotubes). The examples of such materials are mesoporous and activated carbons, clays and zeolites, ion-exchange membranes, carbon nanotubes, and metallic nanoparticles and their composites, respectively.…”

Development of Lignin-Based Mesoporous Carbons for the Adsorption of Humic Acid

et al. 2021

There is an increasing urge to make the transition toward biobased materials. Lignin, originating from lignocellulosic biomass, can be potentially valorized as humic acid (HA) adsorbents via lignin-based mesoporous carbon (MC). In this work, these materials were synthesized for the first time starting from modified lignin as the carbon precursor, using the soft-template methodology. The use of a novel synthetic approach, Claisen rearrangement of propargylated lignin, and a variety of surfactant templates (Pluronic, Kraton, and Solsperse) have been demonstrated to tune the properties of the resulting MCs. The obtained materials showed tunable properties (BET surface area: 95–367 m 2 /g, pore size: 3.3–36.6 nm, V BJH pore volume: 0.05–0.33 m 3 /g, and carbon and oxygen content: 55.5–91.1 and 3.0–12.2%, respectively) and good performance in terms of one of the highest HA adsorption capacities reported for carbon adsorbents (up to 175 mg/g).
