Abstract：In the present paper, the spectral behavior of cadmium with trimethoxyphenylflurone (TM-PF) in microemulsion was studied. In the buffer medium of borax-NaOH at pH 10.40，cadmium (Ⅱ) reacts with TM-PF to form a stable 1∶2 complex. Its apparent molar absorptivity is 6.10×104 L·mol-1·cm-1 at 560 nm. Beer’s law is obeyed in the range of 0-0.60 μg·mL-1. The coexistent metal ions can be separated, and cadmium can be enriched by sulfhydryl dextrane gel (SDG), greatly improving the selectivity and sensibility of the system. The method possesses high sensitivity as well as high selectivity, and can be used to determine trace amount of cadmium in environmental samples successfully.
