Viability of Low Cost Adsorbents for the Removal of Toxic Pesticides in Environmental Matrices - A Review

Abstract

In the present review article the use of low cost adsorbents derived from various materials and chemically modified adsorbents for the removal of toxic pesticides of various classes from environmental matrices has been reviewed. Innumerable pesticides may appear as serious toxic pollutants in water sources, having detrimental impacts on various life forms and even human health because of their toxicity, carcinogenicity, and mutagenicity or causing aesthetic problems such as taste and odors. These toxic pesticides pollute various segments of environment and they can be removed in aqueous media very effectively using different low-cost adsorbents and as well as chemically modified low cost adsorbents derived from various sources. It is evident from the  literature survey of recently published papers those low-cost adsorbents have demonstrated outstanding removal capabilities for pesticides. An attempt was made to formulate few low cost adsorbents which are effectively used in the removal of toxic pesticides from aqueous media.
