In this study, activated carbon derived from mangosteen peel (abbreviated as ACMP) was successfully fabricated. This as-prepared ACMP possessed graphite and had a porous structure with specific surface area of 419.8554 m2/g. Investigations the influencing factors on ciprofloxacin (CIP) adsorption capability based static method showed that: equilibrium can be achieved in 60 min, optimal pH for C...

Nanoporous carbon derived from Moringa oleifera seed waste was synthesized by an original process of flash pyrolysis followed zinc chloride impregnation. The N2-adsorption–desorption results the optimized sample revealed a BET surface area 699.6 m2/g and pore size 2 nm. It evaluated for adsorption mono azo dye, methyl orange (MeO), aqueous solution. Four isothermal models (Langmuir, Freundlich,...

Abstract This work focuses on investigating the feasibility of using a crosslinked amidoximated copolymeric hydrogel as potential adsorbent to recover uranium and thorium ions from aqueous media. The was synthesized via gamma-irradiation copolymerization characterized through FTIR, TGA, SEM. medium acidity notably affected adsorption capacity both ions. data in line with pseudo-1st-order equati...

The present article serves the purpose of pursuing Geometrization of heat flow on volumetrically isothermal manifold by means of RF approach. In this article, we have analyzed the evolution of heat equation in a 3-dimensional smooth isothermal manifold bearing characteristics of Riemannian manifold and fundamental properties of thermodynamic systems. By making use of the notions of various curva...

The role of enzyme engineering in biotechnology, biological and pharmaceutical process cannot be over emphasized. This study compared the adsorption of digestives enzymes; amylase, protease and lipase on to Zn-ferrite (ZnFe2O4). The metal ferrite was synthesized via a sol-gel technique and characterized with scanning electron microscopy (SEM), X-ray diffraction (XRD), Electron paramagnetic reso...

To study the influence of different organic-inorganic composition on adsorption in shale, taking Niutitang Formation shale Huijunba syncline southern Hanzhong as research object, based acid treatment to extract kerogen and wet chemicals. Extracting mineral components by oxidation method, a series isothermal experiments were carried out original rock, kerogen, samples. Through three-dimensional ...

The ZnO-SnO2-Fe2O3 composites containing flower-like particles were prepared by the non-isothermal polymer-salt method. Thermochemical processes proceeding during synthesis was studied DTA/TG structure and morphology of obtained SEM XRD analysis. Prepared small amounts SnO2 Fe2O3 demonstrate high adsorption photodecomposition organic dye Rhodamine 6G in its solutions. Obtained materials show ab...

a comparison was made between the experimental non-isothermal a vs. t curves and those calculated on the basis of a previous isothermal study. It was observed that for low heating rates, when the "thermal lag" is negligible, the dynamic measurements are in good agreement with the isothermal ones. Furthermore, for process (I), two mathematical methods proposed for the interpretation of the non-i...

We derive a continuum sharp-interface model for moving contact lines with soluble surfactants in thermodynamically consistent framework. The consists of the isothermal two-phase incompressible Navier-Stokes equations fluid dynamic and bulk\slash surface convection-diffusion surfactant transportation. interface condition, slip boundary angle adsorption\slash desorption condition are derived base...

We study isothermal transport of a nonelectrolyte binary fluid mixture, which lies in the homogeneous phase near demixing critical point, through capillary tube connecting two reservoirs. Usually, one component is preferentially adsorbed onto wall, and adsorption becomes significant owing to large osmotic susceptibility. The mixture flowing out rich preferred when flow driven by pressure differ...
