| 中文摘要: |
| 近年来，薄膜扩散梯度（DGT）技术取得快速的发展，成为最常用的被动采样技术之一。本文详细阐述了DGT在技术方面的研究进展，包括DGT装置构型、固定相和扩散相材料发展、环境样品的前处理与DGT装置放置、DGT样品处理与测定等，针对该技术前期发展存在的不足，提供了有利于DGT操作和功能提升的系统解决方案，同时对未来的发展进行了展望。 |
| 英文摘要: |
| In recent years, the diffusion gradient in thin films (DGT) has been developed rapidly, making it one of the most commonly used passive sampling techniques. In this paper, the technological research progress of DGT is described in detail, including the configuration of DGT, the development of binding and diffusive phase materials, the pretreatment of environmental samples and the placement of DGT device, the treatment and determination of DGT samples, etc. In view of the shortcomings of the early development of this technology, the paper provides a system solution that is beneficial to the operation and function improvement of DGT. At the same time, the future development of the system is prospected. |
