摘要:

将新型荧光探针PTAID以固态形式用于检测土壤中的钯离子（Pd²⁺）和铜离子（Cu²⁺），检出限分别为 0.63 和1.19 μmol/L，说明探针PTAID对Pd²⁺ 和Cu²⁺有很高的灵敏度。通过条件优化实验，说明探针PTAID在pH值为4.0～12.0，反应时间为0～15 min内可以快速检测Pd²⁺和Cu²⁺。对土壤样品中的Pd²⁺和Cu²⁺进行检测，该方法与电感耦合等离子体发射光谱法相比，准确度和精密度均较高，具有响应时间短、灵敏度高、选择性好等优点，在土壤重金属检测方面具有广阔的应用前景。

Abstract:

A novel fluorescent probe PTAID was successfully used to detect Pd²⁺ and Cu²⁺ in soil by solid form. The detection limits of PTAID for Pd²⁺ and Cu²⁺ were 0.63 and 1.19 μmol/L， respectively， indicating that the probe PTAID had high sensitivity to Pd²⁺ and Cu²⁺. Experiments on condition optimization showed that the probe PTAID can quickly detect Pd²⁺ and Cu²⁺ in the range of pH 4.0~12.0 and the reaction time is 0~15 min. Compared with ICP-OES method， it has higher accuracy and precision， and has the advantages of high sensitivity， strong selectivity， fast and strong anti interference.
