Abstract

Pesticides are an integral part of modern agriculture
in most countries as a tool for controlling pests. In the last few decades,
increasing use of pesticides is polluting environment and water resources day
by day. Adsorption is one of the most used method for removal of these
pollutions due to the simple ease of processing, low cost and effective even in
very low concentrations. Active carbon is very efficient adsorbent for removing
pesticides from aqueous solutions thanks to its high surface area and porosity.
However, the high cost of active carbon can be sometimes restricted for several
purposes.

In recent years, research on the production of low
cost adsorbents alternative to commercially available activated carbon has
increased. Therefore, in this work, peanut shells were used as an adsorbent for
removing 2,4-dichlorophenoxyacetic
acid (2,4-D) from aqueous solutions. The adsorption
performance was studied depending on initial concentrations of 2,4-D solutions.
