Zearalenone (ZEN) is a mycotoxin produced by Fusarium species, commonly found in food, feed, and water bodies. Due to its classification as carcinogen, ZEN hazardous contaminant that requires removal from aqueous food-related effluents. To prevent release into aquatic systems, effective tertiary treatment methods are essential. This study investigates the of using two advanced technologies: adsorption photocatalysis. Two carbonaceous materials derived avocado seed residues (BC BCA) were synthesized characterized SEM, BET, XPS techniques. The capacity BC was determined be 60.23 μg g⁻1, while BCA exhibited 64.96 modeled Freundlich isotherm. Both achieved efficiencies 65 ± 5 % for 70 BCA, influenced pH, temperature, initial concentration. Photodegradation results showed 95 0.68 98 0.36 highlighting critical role light intensity degradation. underscores potential through technologies, representing significant step towards sustainable environmentally friendly remediation. Furthermore, process demonstrated reusability over 17 cycles, photocatalytic promise long-term use, with up 20 reuse cycles.

Abstract The present study investigates the potential of an agricultural by product cassava stem biochar, as effective adsorbent for removal boron from produced water. Cassava biochar was prepared through controlled pyrolysis, and adsorption experiments were conducted to evaluate ions water, considering parameters, such pH (1–8), contact time (0–45 min), initial concentration in water (1.3–3.8 mg/L), dosage (0.25–1.5 g/L), temperature (20–40 °C), agitation speed (50–250 rpm) particle size (125–2000 μm). results revealed that exhibited a significant capacity 3.42 mg/g ions, with notable influence solution pH, time, dosage, temperature, speed, 6, 35 min, 1.25 g/L, 25 °C, 100 rpm, 250 μm, respectively. Freundlich isotherm pseudo‐second order kinetic models applied elucidate mechanism. Thermodynamic parameters also determined gain insights into energetics process, it is exothermic, feasible, spontaneous. Hence, this contributes development cost‐effective remediation boron‐contaminated

Sequestration of cyanide ions from aqueous medium by physio-chemically fabricated biochar of peels of banana and grape fruit in ecofriendly way

International Journal of Phytoremediation, Journal Year: 2024, Volume and Issue: 26(10), P. 1701 - 1715

Pakistan is an agricultural country producing plenty of fruits, like: mango, banana, apple, peaches, grapes, plums, variety citrus fruits including lemon, grapefruit, and oranges. So far the peels most are usually wasted not properly utilized anywhere. In this work, banana grapefruit converted into biochar by slow pyrolysis under controlled supply air used for sequestering cyanide ions from aqueous medium after chemical modification with ZnCl2 sodium dodecyl sulfate (SDS). The modified was characterized various instrumental techniques, SEM, FTIR, TGA, CHNS. Different parameters, time, temperature, pH, dose adsorbent affecting adsorption ions, onto prepared were optimized to understand phenomenon, kinetic thermodynamic studies performed. Concentration estimated employing standard ion selective electrode system it found that Sodium Dodecyl Sulfate treated shown more capacity, i.e.,: 17.080 mg/g as compared all samples. Present work revealed produced fruit waste has sufficient potential eliminate trace quantities water, especially treatment sulfate.
