Accurate recognition and speciation anal. of heavy metal ions in complex hydrol. environments is always a serious challenge. Here, we propose a small mol. based ultrasensitive colorimetric detection strategy, and apply to the accurate detection of Fe2+, Fe3+, Co2+ and Hg2+ in groundwater through the specific recognition of multiple ligands for different metals. The detection limits for Hg2+, Co2+, Fe2+ and Fe3+ are calculated as 6.51, 0.34, 0.49 and 1.01 ppb, resp., which are far below the drinking water standards and superior to most of the reported colorimetric sensors. The speciation anal. of Fe2+/Fe3+ also was realized by a 1-step method without complex pretreatment. The speciation and concentration of Fe2+ and Fe3+ in actual water samples can be accurately identified and monitored. For a visual on-site detection, we developed a simple test strip and applied to visual monitoring of 4 metals with the detection limit estimated by the naked eye as low as ppb-levels. This colorimetric method realizes the rapid, sensitive and portable multiple metal recognition and Fe2+/Fe3+ speciation anal., displaying great potential for on-site rapid water quality anal.
