Abstract Walnut is among the four most consumed dry fruits around globe. Apart from edible walnut kernel, fruit consists of a shell (WS) and husk/hull (WH), usually discarded in processing consumption. These by-products are filled with beneficial compounds that find their use different fields. This review summarizes recent developments research on functional aspects waste (shell husk/hull) various WS has many important bioactive compounds, including lignin, cellulose, oleic, palmitic acids. The creation carbon-based materials, such as activated carbons unmodified/modified WS, adsorbents have been explored. Possible uses for WS-derived include all-natural but powerful eliminating hazardous substances, heavy metals, dangerous synthetic industrial colors. Similarly, WH also like juglone. antioxidant properties can be used textile protein strainers. wastes agriculture, laboratory, medical, food industries, which employed sustainable environment-friendly alternatives.

Characterization and Co-Adsorption Mechanism of Magnetic Clay-Biochar Composite for De-Risking Cd(II) and Methyl Orange Contaminated Water

International Journal of Molecular Sciences, Journal Year: 2023, Volume and Issue: 24(6), P. 5755 - 5755

Published: March 17, 2023

The application of the adsorption method in sewage treatment has recently become a hot spot. A novel magnetic clay-biochar composite (BNT-MBC) was fabricated by co-pyrolysis bentonite and biomass after being impregnated with Fe (NO3)3·9H2O. Its capacity for Cd(II) methyl orange approximately doubled, reaching maximum 26.22 63.34 mg/g, could be easily separated from solution using external magnets its saturation magnetization 9.71 emu/g. series characterizations including surface morphology pore structure, elemental analysis, functional group analysis graphitization were carried out, showing that specific area increased 50 times loading 20 wt.% bentonite, while oxygen-containing groups also enhanced. isotherm fitting indicated adsorbed multiple layers, both monolayer multilayer adsorptions. kinetic chemisorption rate-limiting step both, it complex process controlled two steps intra-particle diffusion. In binary system orange, co-existing pollutants facilitated original one, there no competition between sites orange. BNT-MBC exhibited good reusability can magnetically recovered recycling. Thus, is cost-effective promising adsorbent simultaneous removing wastewater.

Highly Efficient Adsorption of Norfloxacin by Low-Cost Biochar: Performance, Mechanisms, and Machine Learning-Assisted Understanding

ACS Omega, Journal Year: 2024, Volume and Issue: 9(28), P. 30813 - 30825

Published: July 5, 2024

This study employed potassium carbonate (K2CO3) activation using ball milling in conjunction with pyrolysis to produce biochar from one traditional Chinese herbal medicine Atropa belladonna L. (ABL) residue. The resulting KBC800 was found possess a high specific surface area (SBET = 1638 m2/g) and pore volume (1.07 cm3/g), making it effective for removing norfloxacin (NOR) wastewater. Batch adsorption tests confirmed its effectiveness eliminating NOR, along excellent resistance interference impurity ions or antibiotics. Notably, the maximum experimental NOR capacity on 666.2 mg/g at 328 K, surpassing those of other materials reported. spontaneous endothermic could be better suited Sips model. Additionally, adsorbs mainly by filling, electrostatic attraction, π–π EDA interactions, hydrogen bonds also contributing significantly. machine learning model revealed that significantly affected initial concentration, followed SBET average size. Based random forest model, is demonstrated able adsorb effectively. It noteworthy use low-cost pharmaceutical wastes adsorbents emerging contaminants such as antibiotics have greater potential future practical applications under ongoing dual carbon policy.
