An overview of potentiometric sensors that are capable of detecting toxic heavy metal ions in environmental samples is presented and discussed. Notwithstanding the tremendous work performed so far, it is obvious that still several limitations do exist in terms of selectivity, limits of detection, dynamic ranges, applicability to specific problems, and reversibility. A survey on important advances in potentiometric sensors with regard to high selectivity, lower detection limit, fast response time, and on-line environmental analysis is presented in this review article.

本文介绍并讨论了能够检测环境样品中有毒重金属离子的电位传感器。尽管迄今为止已经开展了大量工作，但显然在选择性、检测限、动态范围、对特定问题的适用性以及可逆性等方面仍然存在一些限制。本文综述了电位传感器在高选择性、低检测限、快速响应时间和在线环境分析方面的重要进展。[本文提供补充材料。请访问《分析化学评论》的出版商在线版本以查看免费的补充文件。]
