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.
