Removal of Organic Pollutant from Water by Modified Bentonite

Abstract

Bromoxynil is a nitrile herbicide, widely used in the region for annual weed control. Its application creates environmental contaminations. For instance, it was detected in air samples [1], water samples [2], and soil samples [3]. It application may create health problems [4]. Furthermore, bromoxynil has been reported as a toxic agent to important green algae in the ecosystem [5], more over, it is recently indicated that bromoxynil was among eight-herbicide mixture, that produced negative effects on microbial communities even at low concentrations [6].
