摘要：
The removal of pesticide imazethapyr from wastewater under different batch experimental conditions, using an activated carbon was investigated. The pesticide under study was imazethapyr which is a well known herbicide in Moroccan agriculture. The adsorbent was activated carbon. It was determined that the adsorption of imazethapyr was slightly pH dependent. Different experimental parameters like initial pH, contact-time and initial concentration on the adsorption of imazethapyr were evaluated. It was found that the rate of sorption of imazethapyr onto activated carbon is very fast with almost 94 % adsorption taking place in the first 10 min at pH = 3. The applicability of the Langmuir isotherm for the present system has been evaluated at different concentrations.
