This paper describes the performance of Granular Activated Carbon (GAC) to adsorb and separate glucose and maltose solutes from the industrial effluents by adsorption process. In this study, the capability of Granular Activated Carbon (GAC) to adsorb glucose and maltose were experimentally examined. Commercial GAC (mesh 12-20), supplied by Sigma Aldrich company in...
Nitrate contamination of water resources and the growing concentration of nitrate endanger human health and the environment and considering its reduction strategies from water resources is important. The aim of this study was to investigate the possibility of removal of nitrate from aqueous solutions using granular activated carbon from grape wood coated with iron nanoparticles. The results sho...
the adsorption properties and mechanics of selected endocrine disrupting compounds; 17 β-estradiol, 17 α – ethinylestradiol and bisphenol a on locally available black tea leaves waste and granular activated carbon were investigated. the results obtained indicated that the kinetics of adsorption were ph, adsorbent dose, contact time and temperature dependent with equilibrium being reached at 20 ...
The adsorption of the fungicide Carbendazim (CBZ) on granular activated carbon (GAC) coconut shell was investigated through batch tests in deionized water. most favorable conditions for CBZ were examined variation mass GAC, temperature, and contact time. Response Surface Methodology (RSM) applied, seeking best condition to optimize future tests. A thermodynamic analysis carried out using Van't ...

Granular activated carbons are a very versatile group of adsorbents, with capability for selectively adsorbing thousands of organic and certain inorganic materials. From medicinal uses of powdered carbons in ancient Egypt, through charred interiors of whiskey barrels, carbon has been activated and used as an adsorbent for centuries. Granular vapor phase activated carbon media was first widely u...
We explore the use of Granular Activated Carbon (GAC) as a mitigation technique for the treatment of drinking water that was artificially enriched with Rn-222 in laboratory by placing a radium rich granite stone (pitchblende) in a closed container filled with tap water for several days in order to allow Rn-222 concentration to approach its highest possible level. Granular Activated Carbon (GAC)...
an improved chemical regeneration of the granular activated carbon (gac) exhausted by the color (pigments and pollutants) from citric acid fermentation solution (caf) was investigated. in the experiments, improved means were adopted to advance the traditional chemical regenerating method and the adsorption capacity of the first time renewed gac is 103% of original gac. using oxidant and surfact...
this paper describes laboratory scale experiments examining the impact of microwave irradiation on the granular activated carbon (gac) exposed to toluene, a common organic vapor frequently released into work environment as well as outdoor. a stream containing 300 ppm toluene was supplied and passed through the granular activated carbon. the saturated adsorbent was placed in a quartz glass react...
in this research, the chloroform (chcl3) removal effectiveness of two water treatment systems including membrane technology and granular activated carbon (gac) adsorption were studied. two bench-scales were designed and set up: 1) nanofiltration (nf) spiral-wound modules and 2) gac adsorption column. chloroform was considered as trihalomethanes (thms) basic indicator compound. the inlet and out...
