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Pd2+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. |
