Abstract In this study, the removal of bisphenol A (BPA), 2,4-dinitrophenol (2,4-DNP), and 2,4-dichlorophenol (2,4-DCP) using a new magnetic adsorbent methacrylic acid-functionalized β-cyclodextrin (Fe 3 O 4 @MAA-βCD) was evaluated. The materials were characterized by Fourier transform infrared spectroscopy, scanning electron microscope, transmission microscopy, X-ray diffraction. batch adsorpt...

A key parameter for calculating the swelling deformation using fractal model is dimension. Small angle X-ray scattering (SAXS) and liquid nitrogen adsorption method (Frenkel-Halsey-Hill (FHH) Neimark thermodynamic method) were employed to determine dimension of four Chinese bentonite. Based on SAXS FHH method, was adopted predict mechanical behavior. The result suggested that dimensions #1, #2,...

In 1996, Lord Woolf described a vision for civil English and Welsh justice, culminating in his culture-changing reforms (the Reforms) the Civil Procedure Rules of April 1999. These impose continuing duty on litigants to consider alternative dispute resolution (ADR) preference litigation, even after it has commenced, courts, encourage ADR. duties are central method delivery justice. They require...

Abstract This study investigated the performance of jute stick charcoal (JSC) as a biosorbent for removal hexavalent chromium [Cr(VI)] from an aqueous solution. The batch adsorption experiment was conducted by influencing various experimental conditions like contact time (5–240 min), pH (2–8), initial Cr(VI) concentration (10–100 mg/L), and JSC dose (2–10 g/L). result shows that maximum (99%) f...

Sabit sıcaklık ve bağıl nem ortamı sağlayan bir kamarada baklanın (Vicia faba L.), sorpsiyon özellikleri; üç farklı sıcaklıkta (25, 35 45 °C) nemi atomizer nemlendirici ile ayarlanarak su aktivitesi değerlerinde (0.1-0.9 aw) incelenmiştir. Elde edilen deneysel verilerden izoterm eğrilerinin, BET buharı izotermleri sınıflandırmasına göre Tip III (J şekilli) özelliğe sahip olduğu bulunmuştur. Bel...

Understanding sorption isotherms is crucial in food science for optimizing the drying processes, enhancing shelf-life of food, and maintaining quality during storage. This study investigated sweet cherry powder (SCP) using static gravimetric method. The experimental water curves lyophilized were determined at 30°C, 40°C, 50°C. then fitted to six isotherm models: Modified GAB, Halsey, Smith, Osw...

In this study, commercial zinc oxide nanoparticles were used. Various techniques such as AFM, XRD, and FTIR employed to characterize their surface studies. From the XRD analysis, each reflection peak with relative intensity of different planes determined presence ZnO spectrum revealed that particle size was about (27.43 nm), which is in good agreement those estimated from AFM analysis. It showe...

The adsorption pore structure is the key affecting technology of enhanced coal bed methane recovery (ECBM). In this paper, nitrogen measurement (NAM) and low-field nuclear magnetic resonance (NMR) methods are used to test structural parameters pores four samples with different metamorphic degrees. Combining fractal theory, applicability physical significance dimensions obtained from models anal...
