The effects of oxidation using HNO3 on the properties of the carbonized wheat and barley
straw were investigated by measuring different properties such as specific surface area …

The present study deals with the adsorption of Cr (VI) on carbonized wheat straw (CWS) and
barley straw (CBS). Carbon materials, prepared at different carbonization temperatures …

Surface modification of activated carbon (AC) could be done through different methods in
order to modify their specific physical and chemical properties to facilitate metals removal …

In the present study, the removal of Pb (II) ions on oxidized activated carbons (ACs) was
investigated. ACs were derived from activation of indigenous cotton stalks waste with …

A number of activated carbons were prepared from a locally available by-product, corncobs,
under currently established activation schemes. Obtained carbons were characterized by N2 …

The aim of this study is producing the low-cost activated carbon rice husks by chemical
activation using zinc chloride (ZnCl2) at 700 C in N2 atmosphere. Impregnation ratios of 1: 1 …

In aqueous systems, chromium usually exists in both trivalent and hexavalent oxidation
states, being Cr (VI) of particular importance and concern due to its great toxicity. Industrial …

In this study, teff (Eragrostis tef) straw has been chemically treated and tested as an
adsorbent for Cr (VI) removal. Chemically treatment of teff straw was done by NaOH, H 3 PO …

The removal of Cr (VI) from aqueous solution by rice straw, a surplus agricultural byproduct
was investigated. The optimal pH was 2.0 and Cr (VI) removal rate increased with …

Activated carbon derived from pine cones waste was prepared by carbonization at 450° C,
activated by different activating agents: ZnCl 2, H 2 SO 4 and NaOH, and then pyrolyzed at …
