Diuron is one of the most common herbicides used in agriculture with long persistence and high toxicity causing a certain hazard to the environment. Thus, this is necessary to control the residue levels of diuron in a natural environment. To achieve this goal, a diffusive gradient in thin-films technique (DGT), as a new method for in-situ sampling, is described in this paper, which can provide the time-weighted average concentration of target compounds in the sampling period. DGT consists of XAD18 resin gel can accumulate up to 73.58 ug diuron in lab conditions and without significant negative performance under varies range of pH (4 to 9), ionic strength (0.001 to 0.5 mmol L⁻¹) and dissolved organic matter(0–20 mg L⁻¹). The string rate of more than 100 rpm indicated the DGT will not likely be affected by flow rate in the aquatic environment. The study successfully indicates the DGT’s performance on diuron, providing a promising technique for future investigation of distribution and occurrence in the natural environment.

敌草隆是农业上最常用的除草剂之一，持久性强，毒性高，对环境有一定危害。因此，这对于控制自然环境中敌草隆的残留水平是必要的。为了实现这一目标，本文介绍了一种扩散薄膜技术（DGT）作为原位采样的新方法，该方法可以提供采样期间目标化合物的时间加权平均浓度。DGT由XAD18树脂凝胶组成，在实验室条件下可累积多达73.58 ug的diuron，并且在各种pH范围（4至9），离子强度（0.001至0.5 mmol L ^-1）和溶解的有机物（0– 20毫克L ^-1）。线速度超过100 rpm表示DGT在水生环境中不会受到流速的影响。该研究成功地表明了DGT在敌草隆上的性能，为将来研究自然环境中的分布和发生提供了有希望的技术。
