In this research paper, an experimental breakthrough curve for citric acid in an adsorption recovery process was determined by an ion-exchange resin in 20, 35, 55 °C. Also, a mathematical model for breakthrough curve was presented. Among ion exchange resins that have been experienced, many weak and strong basic anionic resins are available such as, IRA-92, IRA-93, IRA-420 and IRA-458 and all of...

A moisture equilibration test has been designed to study the pore structure and adsorption capacity of organic-rich shale with different contents. Five humidity environments were artificially controlled obtain samples With N 2 adsorption/desorption, differences in contents compared analysed. The results showed that diameter 2–10 nm pores decreased increasing characteristics conformed GAB model....

Abstract Contamination with Cd, Cu and Pb is a major environmental issue. Cations of those metals may adsorb on negatively charged surfaces polymeric silicic acid (pSi), altering their fate. Aiming to elucidate the underlying mechanisms extent adsorption, we conducted batch adsorption experiments at pH 4 6 concentrations that excluded precipitation solid phases. Zeta-potential measurements were...

This study is to prepare chitosan beads modified with sodium dodecyl sulfate (SDS) effectively remove Cr(III) from an aqueous solution. The characterizations of SDS-chitosan by scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDS), Fourier transform-infrared (FT-IR) and photoelectron (XPS) proved the successful synthesis adsorbent. adsorption on SDS material was investigat...

In designing amine-incorporated adsorbents for CO2/CH4 separation, it is essential to understand the individual effects amine moieties have on separation of mixtures. this work, primary, secondary, and tertiary amines are moderately grafted SBA-15 examine factors affecting adsorption CO2 CH4. Materials were characterised by thermogravimetric elemental analysis, their performance was measured vo...
