Synthesis Fe3O4/Talc nanocomposite by coprecipition-ultrasonication method and advances in hexavalent chromium removal from aqueous solution
Adsorption Science and Technology - Tập 38 Số 9-10 - Trang 483-501 - 2020
Huong Nguyen Thi, Nguyễn Ngọc Sơn, Vo Hoang Phuong, Công Tiến Dũng, Phạm Thị Mai Hương, Lê Thanh Sơn
The Fe3O4/Talc nanocomposite was synthesized by the coprecipitation-ultrasonication method. The reaction was carried out under a inert gas environment. The nanoparticles were characterized by X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), fourier-transform infrared spectroscopy (FT-IR) and vibrating sample magnetomet...... hiện toàn bộ
Colour Removal from Dye Wastewater Using Sugar Cane Dust as an Adsorbent
Adsorption Science and Technology - Tập 17 Số 4 - Trang 269-282 - 1999
S. D. Khattri, Maya Shankar Singh
Decolouration of dilute solutions of basic dye stuff was carried out using sugar cane dust as an adsorbent. It was found that low adsorbate concentration, small particle size of the adsorbent, a temperature of 25°C and a pH value of 7.5 for the medium all favour the removal of dye from aqueous solutions. The percentage of dye adsorbed by sugar cane dust decreased from 96.48% to 83.32% and...... hiện toàn bộ
Models for Type VI Adsorption Isotherms from a Statistical Mechanical Formulation
Adsorption Science and Technology - Tập 31 Số 4 - Trang 341-357 - 2013
Manel Ben Yahia, Yosra Ben Torkia, Salah Knani, M.A. Hachicha, Mohamed Khalfaoui, Abdelmottaleb Ben Lamine
In this study, two theoretical expressions for the Type VI isotherm in the IUPAC classification are presented. The formulation of these new expressions is based on a rigorous statistical mechanical description. The expressions allow for the estimation of physicochemical parameters within the theoretical model. The proposed models allow a good correlation to Type VI experimental isotherms ...... hiện toàn bộ
An alternative low-cost adsorbent for gold recovery from cyanide-leached liquors: Adsorption isotherm and kinetic studies
Adsorption Science and Technology - Tập 37 Số 1-2 - Trang 3-23 - 2019
Refiloe Tsolele, Fanyana M. Mtunzi, Michael J. Klink, Vusumzi Emmanuel Pakade
Pristine Macadamia nutshell-based activated carbons were chemically oxidized with different concentrations of H3PO4 and HNO3 to increase their surface adsorption properties and further explore if they could be an attractive alternative low-cost adsorbent for gold recovery from cyanide-leached liquors. The modified activated ca...... hiện toàn bộ
The Dynamic Response and Characteristics of an Oxygen Vacuum Swing Adsorption Process to Step Perturbations. Part 1. Open Loop Responses
Adsorption Science and Technology - Tập 21 Số 4 - Trang 319-347 - 2003
C.C.K. Beh, Paul A. Webley
Oxygen vacuum swing adsorption (VSA) has emerged as an important unit operation in many chemical engineering processes such as iron and aluminium smelting, making oxygen the third largest man-made chemical commodity in the world. Although a mature technology (with the first patents published in the 1970s), oxygen VSA processes are still not well understood due to their complicated batch-l...... hiện toàn bộ
Adsorbents for Industrial Pollution Control
Adsorption Science and Technology - Tập 15 Số 10 - Trang 777-787 - 1997
Mohammad S. El‐Geundi
Adsorbent materials used for treating industrial pollutants are reviewed. The article consists of two parts. The first part considers new trends in traditional adsorbents such as activated carbons and zeolites. New low-cost adsorbents such as waste materials and clay minerals are discussed in the second part. It has been reported that activated carbons can be obtained fr...... hiện toàn bộ
Application of Kinetic Models to the Sorption of Copper(II) on to Peat
Adsorption Science and Technology - Tập 20 Số 8 - Trang 797-815 - 2002
Yuh‐Shan Ho, Gordon McKay
A comparison of the kinetics of the sorption of copper(II) on to peat from aqueous solution at various initial copper(II) concentrations and peat doses was made. The Elovich model and the pseudo-second order model both provided a high degree of correlation with the experimental data for most of the sorption process. There was a small discrepancy at the initial stages of sorption which sug...... hiện toàn bộ
Pore Characterization of Carbonaceous Materials by DFT and GCMC Simulations: A Review
Adsorption Science and Technology - Tập 21 Số 5 - Trang 389-423 - 2003
D.D. Do, H.D. Do
A review is given of the pore characterization of carbonaceous materials, including activated carbon, carbon fibres, carbon nanotubes, etc., using adsorption techniques. Since the pores of carbon media are mostly of molecular dimensions, the appropriate modern tools for the analysis of adsorption isotherms are grand canonical Monte Carlo (GCMC) simulations and density functional theory (D...... hiện toàn bộ
Adsorption of congo red dye from aqueous solutions by prepared activated carbon with oxygen-containing functional groups and its regeneration
Adsorption Science and Technology - Tập 37 Số 1-2 - Trang 160-181 - 2019
Ridha Lafi, Imed Montasser, Amor Hafiane
This study investigates the potential use of activated carbon prepared from coffee waste (CW) as an adsorbent for the removal of congo red dye from aqueous solution. The oxygen-containing groups of activated carbon prepared from CW play an important role in dyes ions adsorption onto activated carbon prepared from CW. The activated carbon is characterized by scanning electron microscopy and...... hiện toàn bộ
Cooperative CO2 adsorption promotes high CO2 adsorption density over wide optimal nanopore range
Adsorption Science and Technology - Tập 36 Số 1-2 - Trang 625-639 - 2018
Lei Chen, Takumi Watanabe, Hirofumi Kanoh, Kenji Hata, Tomonori Ohba
Separation of CO2 based on adsorption, absorption, and membrane techniques is a crucial technology necessary to address current global warming issues. Porous media are essential for all these approaches and understanding the nature of the porous structure is important for achieving highly efficient CO2 adsorption. Porous carbon is considered to be...... hiện toàn bộ
