A Comparative Study of Pd2+ and Cu2+ in Soil by PTAID and ICP-OES
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.
