The effectiveness of rice husk–activated carbon (RHAC) in the adsorption of Cr (VI) from an
aqueous solution was investigated. The adsorbent was prepared, characterized, and …

In this study, Cr (VI) adsorption ability of hazelnut husk carbon (HHC) was examined by
investigating various parameters such as initial pH of the solution, agitation time and initial …

Agricultural and forestry waste biomasses have been widely used as adsorbents for
environmental remediation with the advantages such as sustainability, economic efficiency …

This paper highlights the utility of rice husk ash for the adsorption of Cr (VI) ions from
aqueous solutions. Rice husk ash (RHA) is produced when rice husk is burnt for various …

This study investigated the removal of hexavalent chromium (Cr (VI)) by rice husk and rice
husk ash from aqueous solution using different doses of adsorbent (5–25 g/L), initial Cr (VI) …

This research investigated the adsorption of Cr (VI) using HNO 3 0, 01 M-activated rice straw
in a batch system. Some parameters such as pH, initial Cr (VI) concentration, and contact …

The removal of Cr (VI) from aqueous solution by batch adsorption technique using different
low-cost adsorbents was investigated. Adsorbents such as clarified sludge—a steel industry …

In the present work, a new low-cost activated carbon was prepared from paper mill sludge in
order to remove Cr (VI) ions from aqueous solution. The effects of adsorbent dosage, pH …

Synthesized activated carbon from silver berry (Elaeagnus angustifolia L.) seeds (ACSBS)
was used as a low-cost adsorbent for the removal of hexavalent chromium (Cr (VI)) in …

Activated carbon (AC) prepared from coconut tree sawdust was used as an adsorbent for the
removal of Cr (VI) from aqueous solution. Batch mode adsorption studies were carried out by …
