Preparation of active carbons from corn stalk for butanol vapor adsorption

Preparation and characterization of activated carbons from corn cob

Preparation, characterization and phenol adsorption capacity of activated carbons from African beech wood sawdust

In the present study, different activated carbons were prepared from carbonized African beech wood sawdust by potassium hydroxide activation. The activated carbons were characterized by brunauer–emmett–teller, scanning electron microscope, fourier transform infrared spectroscopy, and thermogravimetric analyzer. The phenol adsorption capacity of the prepared carbons was evaluated. The d...

Dissolving Pulp (alpha-cellulose) from Corn Stalk by Kraft Process

Corn stalk can be used as an alternative non-wood raw material to produce cellulosic dissolving grade pulp. In this work, the potential of corn stalk in the production of dissolving pulp (alpha-cellulose) was investigated. It was collect ed from a corn stalk farm of Kermanshah, Iran. The sequences of experimental work were: water and acid prehydrolysis at 160˚C for 30min, followed by Kraft pulp...

Adsorption Efficiency of Iron Modified Carbons for Removal of Pb(II) Ions from Aqueous Solution

Abstract Introduction: The Lead causes severe damage to several systems of the body, especially to bony tissues. Until now, several low-cost biosorbents have been studied for removal of heavy metal ions from aqueous solutions. In the present study, carbonized pomegranate peels modified with Fe2+ and Fe3+ ions and then it was investigated for removal of Pb(II) ions from aqueous solution. ...

Adsorption Characterization of Active Carbons Modified by Deposition of Silica

Surface properties carbonaceous materials are often modified by chemical deposition in order to expand the range of their applications | 11. However, the exact nature of the chemical deposition process is not completely understood. The layers of deposited material may exhibit a high degree of inhomogeneity., which results in inadequate performance of the modified material in the targeted applic...
