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 …

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 …

The removal of Cr (VI) from wastewater by adsorption from agro-industrial residues remain
an attractive option since combines reasonable cost with the quality of effluents treated. This …

Removal of Cr (VI) from aqueous solutions has been investigated by adsorption on a low-
cost adsorbent, calcined rice husk (CRH). Rice husk is an agrowaste material. It was …

The removal of Cr (VI) from aqueous solution using sulphonated black rice husk ash
(SBRHA) and sulphonated white rice husk ash (SWRHA) at various pH and adsorbent …

Adsorption behavior of chromium, Cr (VI) from wastewater has been investigated using
clarified sludge (a steel plant waste material), rice husk ash and sawdust as non …

In recent years, the release of heavy metals into the aquatic environment has become a
major issue. Numerous socio-economic problems are caused due to the presence of several …

Rice husk, an agricultural solid waste was used as sorbent for the removal of chromium (VI)
from aqueous solution after modification with HCl. The results of the experiments showed …

The potential to remove Cromium (Cr) VI from aqueous solution by using activated rice husk
was investigated in batch experiments. Rice husk (Oryza sativa) of Kernel Basmati brand …

Present study dealt the removal of Cr (VI) in a tannery industry wastewater using rice husk
silica powder as adsorbent. The experimental investigations have been carried out by using …
