cellulose wastes of a wood and paper factory were used to produce activated carbon. several chemical agents under various conditions were used for production of activated carbon and hence their adsorption properties have been evaluated. in addition the effect of process parameters such as raw material, chemical agent concentration, impregnation ratio, carbonization temperature, carbonization ti...

today the industrial wastes are one of the main problems in the developing countries. discharging the industrial wastewater into environment is harmful for human health and other living creatures.thus decreasing of the pollution load of waste waters is an important environmental issue.adsorption of chemical oxygen demand by biomass wastes can be a proper and low cost method for cod removal from...

The present work was carried out to evaluate the removal of p-nitrophenol by adsorption onto olive cake based activated carbon having a BET surface area of 672 m²/g. The batch adsorption experimental results indicated that the equilibrium time for nitrophenol adsorption by olive cake-based activated carbon was 120min. The adsorption data was modeled by equilibrium and kinetic models. The pseudo...

Adsorption of Chromium ions (VI) and (III) in aqueous solution was investigated using activated carbon prepared from olive wastes, by one step physical activation with steam. After adsorbent material characterization using adsorption capacity of methylene blue, iodine and phenol, BET surface area, Fourier Transform InfraRed (FT-IR) spectroscopy, pHpzc, surface functions based on the Boehm m...

In this study, activated carbon synthesized from Aloe vera green wastes was used as a sorbent to remove 4-chlorophenol (4-CP) from aqueous solutions. The influence of contact time (0-100 minutes), pH (2-8), adsorbent dosage (1-9 g/l), and initial 4-CP concentration (10-60 mg/l) in batch system was investigated on the sorption. The sorbent was specified using scanning electron microscopy (SEM). ...

The olive pomace is produced as a result of oil production. Studies, about products obtained from agricultural wastes, have increased within the scope zero waste studies. In present study, activated carbon was synthesized using taken processing plant operating with three-phase process. characterization performed Scanning Electron Microscope (SEM), Fourier-Transform Infrared Spectroscopy (FT-IR)...
