Abstract

Pesticides from diffuse pollution sources adsorbed in suspended particles flow into surface water and threats to the public health. In this research, dechlorination constants of Atrazine by zero valent iron were measured with addition of buffer solution for simulating buffer capacity of sediment. When initial concentration of Atrazine was 10, 30, and 50 mg/L, their dechlorination was explained using the pseudo-first order reaction. Dechlorination constants $K_{obs}$ were $3.21{\times}10^{-2}/d$ in average.

비점오염원에서 배출되는 농악은 부유물질과 흡착하여 퇴적되며 수체로 유출되어 공공 보건에 위해를 미친다. 본 연구에서는 0가 철이 퇴적물에 포함된 농약의 일종인 아트라진을 분해하는 속도를 구하고자 하였으며 이때 퇴적물의 완충능력을 모사하기 위하여 완충액을 첨가하여 pH를 중성으로 하였다. 아트라진의 초기농도를 10, 30, 50 mg/L로 할 때 아트라진의 감소는 가1차 반응을 따랐으며 반응속도상수 $K_{obs}$는 평균 $3.21{\times}10^{-2}/d$를 나타내었다.
