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(Pd^(2+))和铜离子(Cu^(2+)),检出限分别为0.63和1.19μmol/L,说明探针PTAID对Pd^(2+)和Cu^(2+)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Pd^(2+)和Cu^(2+)。对土壤样品中的Pd^(2+)和Cu^(2+)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。A novel fluorescent probe PTAID was successfully used to detect Pd^(2+)and Cu^(2+)in soil by solid form.The detection limits of PTAID for Pd^(2+)and Cu^(2+)were 0.63 and 1.19μmol/L,respectively,indicating that the probe PTAID had high sensitivity to Pd^(2+)and Cu^(2+).Experiments on condition optimization showed that the probe PTAID can quickly detect Pd^(2+)and Cu^(2+)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.
