Chemical Regeneration of Exhausted Granular Activated Carbon Used in Citric Acid Fermentation Solution Decoloration
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 oxidan...
متن کاملOptimization of chemical regeneration procedures of spent activated carbon
The chemical regeneration of granular activated carbon exhausted in a petrochemical wastewater unit was investigated. Gas chromatography and energy-dispersive X-ray spectroscopy demonstrated that spent activated carbon carries large types of organic and inorganic materials. Diverse chemical solvents were adopted in comparison with traditional chemical solvents and regeneration efficiency was in...

متن کاملModeling studies for adsorption of phenol and co-pollutants onto granular activated carbon prepared from olive oil industrial waste
Granular activated carbon (OSAC) which was derived from olive oil industrial solid waste was chemically activated with different concentrations of phosphoric acid. OSAC-materials were evaluated for their ability to remove phenol from aqueous solution in a batch technique. Adsorption isotherms were determined and modeled with five linear Langmuir forms, namely the Freundlich, Elovich, Temkin, Ki...
متن کاملTreatment of Reactive Black 5 by combined electrocoagulation-granular activated carbon adsorption-microwave regeneration process.
Treatment of an azo dye, Reactive Black 5 (RB5) by combined electrocoagulation-activated carbon adsorption-microwave regeneration process was evaluated. The toxicity was also monitored by the Vibrio fischeri light inhibition test. GAC of 100 g L(-1) sorbed 82% of RB5 (100 mg L(-1)) within 4h. RB5-loaded GAC was not effectively regenerated by microwave irradiation (800 W, 30s). Electrocoagulatio...
