Abstract: In this paper, configuration of TTP-Co was determinated. Awater insoluble porphyrin (TMDOPP) was synthesized and its color reaction with cadmium was studied. Ahighly sensitive method for determining cadmium at ppm× 10-3 level was established. The simple and rapid method has been succefully applied to the direct determination of trace amount of cadmium in water sample with a satisfactory result.
