Abstract Fava bean peels, Vicia faba (FBP) are investigated as biosorbents for the removal of Methylene Blue (MB) dye from aqueous solutions through a novel and efficient sorption process utilizing ultrasonic-assisted (US) shaking. Ultrasonication remarkably enhanced rate relative to conventional (CV) shaking, while maintaining same capacity. Ultrasonic amounted four times higher than its counterpart at 3.6 mg/L initial concentration, 5 g/L adsorbent dose, pH 5.8. Under dose conditions,...
Marine algae are a rich source of biologically active compounds that can be utilized in various food and pharmaceutical applications. In this study, ultrasound-assisted extraction (UAE) was optimized to maximize yield total carbohydrate content extracted from the red algae,
This study describes the preparation of nanoporous activated carbons from agricultural waste peach stones. These materials were utilized as adsorbents for removing imidacloprid pesticide aqueous media. Two types (PSAC 300 and PSAC 500) synthesized via chemical activation with orthophosphoric acid followed by pyrolysis at 500 °C, respectively. Brunauer, Emmet, Teller (BET) analysis revealed a mesoporous structure lower surface area pore volume than that microporous 300. Both successfully...
This paper describes a novel combined post-extraction process for obtaining bioactive compounds from the aqueous high molecular weight sulfated polysaccharides (SPs) extracts of green algae, Ulva lactuca. After extracting SPs, they were enzymatically hydrolyzed then hydrolysate (V45) was fractionated into eight different fractions (F1-F8) using ion exchange chromatography. Crude SPs together with V45 and examined their carbohydrate, protein, sulfate contents. In addition, degree...
The discharge of contaminants emerging concern (CECs) into water streams is becoming a major global issue. Herein, novel nanoporous membranes bio-based cellulose acetate, poly(lactic acid) and biodegradable polyurethane in-situ impregnated with catalytic cobalt nanoparticles were synthesized tested for the removal Methylene Blue (MB) Congo Red (CR) dyes from water. polymers supported formation network hydrogen bonding among different functional groups as confirmed using FTIR, which improved...
Biogenic copper nanoparticles (Cu NPs) were synthesized using the aqueous crude extract of mangrove leaves, Avicennia marina (CE). GC-MS metabolite profiling CE showed that their carbohydrates are mainly composed D-mannose (29.21%), D-fructose, (18.51%), L-sorbose (12.91%), D-galactose (5.47%) and D-Talose (5.21%). Ultra-fine 11.60 ±4.65 nm comprising Cu2O Cu(OH)2 species obtained with a carbohydrate phenolic content 35.6±3.2% 3.13±0.05 mgGA/g, respectively. The impact biogenic Cu NPs on...
A new modified approach was used to synthesize hydroxyapatite-carbon nanocomposite (HAP-C) by utilizing cement kiln dust (CKD), which is an industrial waste product, as a source of calcium. Calcium from CKD first chelated using citric acid, and the chelate transformed into calcium carbonate carbon calcination at 450 °C for 1 h, then reacted with ortho-phosphoric acid precipitation method, thus serving precursor formation HAP-C. Then, HAP-C calcined various temperatures 2 h after it reached...

Trichoderma virens -synthesized TiO 2 –CuO@GO nanocomposite exhibits potent antibacterial activity and efficiently degrades Congo red via PMS activation.
In this work, we develop chitosan/xylan-coated magnetite (CsXM) nanoparticles as eco-friendly efficient adsorbents for the facile removal of contaminants from water. Characterization CsXM using Fourier Transform Infra-Red (FTIR) Spectroscopy, Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), Thermogravimetric Analysis (TGA), Transmission (TEM), Zeta potential measurements, and Brunauer-Emmet-Teller (BET) analysis, confirmed successful preparation a chitosan/xylan complex coated...
