The tablets were placed in a water column having different concentrations of Pb²⁺和Cu²⁺ions, and the water was allowed to flow for 45 minutes at a flow rate of 100 ml/s. Thereafter, the tablets were dried and made to powder, and their phosphorescence was measured. The gradual stilbene phosphorescence turnoff in the tablets from various concentrations of metal ions was correlated with sorption amounts. The tablets were able to detect effectively metal ions (up to Pb²⁺1.0 mmol/L and Cu²⁺5.0 mmol/L) in the aqueous media. As such, the concentrations of Pb²⁺和Cu²⁺离子含量很低的测试解决方案进行了测定。这种方法提供了实时的金属离子分析，并且不涉及在实验室分析水样的采样。SN - 2090-8865 UR - https://doi.org/10.1155/2020/9712872 DO - 10.1155 /九百七十一万二千八百七十二分之二千○二十○JF - 中华化学PB分析方法 - Hindawi出版KW - ER -
