TL;DR: In this article, slow pyrolysis of agricultural residues such as olive husk, corncob and tea waste at high temperature (950-1250 K) in a cylindrical reactor batch reactor was investigated.
948 citations
TL;DR: In this paper, an acid dye, acid yellow 36, was used as the adsorbate for the removal of acid dyes from aqueous solution and the results showed that a pH value of 3 is favorable for the adsorption of acid dye.

TL;DR: In this article, the role of rice husk and its ash in the removal of various pollutants from wastewater was reviewed and the adsorption mechanism, influencing factors, favorable conditions, etc., discussed.
Abstract: Rice husk, which is a relatively abundant and inexpensive material, is currently being investigated as an adsorbent for the removal of various pollutants from water and wastewaters. Various pollutants, such as dyes, phenols, organic compounds, pesticides, inorganic anions, and heavy metals can be removed very effectively with rice husk as an adsorbent. This article presents a brief review on the role of rice husk and rice husk ash in the removal of various pollutants from wastewater. Studies on the adsorption of various pollutants by rice husk materials are reviewed and the adsorption mechanism, influencing factors, favorable conditions, etc., discussed in this article. It is evident from the review that rice husk and its ash can be potentially utilized for the removal of various pollutants from water and wastewaters.
