This review article describes the work reported on the separation and analysis of heavy metal ions by different modes of thin-layer chromatography (TLC) such as soil, micellar, and reversed-phase TLC during 2000–2019. The history of different modes of TLC has been briefly mentioned. The literature survey reveals that the number of papers reported during 2000–2019 on the separation of heavy metal ions by different modes of TLC follows the trend: micellar TLC > soil TLC > reversed-phase TLC.

薄层色谱法（TLC）对重金属离子的分离和分析—综述（2000–2019）

这篇综述文章介绍了2000-2019年间通过不同模式的薄层色谱法（TLC）分离和分析重金属离子的工作，这些薄层色谱法包括土壤，胶束和反相TLC。简要提到了TLC不同模式的历史。文献调查显示，在2000–2019年间，通过不同模式的薄层色谱分离重金属离子的论文数量呈趋势：胶束薄层色谱>土壤薄层色谱>反相薄层色谱。
