2014The reaction mechanism of Lead ions catalyzing complexation reactions between TIPP and metal ions wasinvestigated by researching the kinetics of the formation of metalloporphyrins by UV/Vis-spectra, and verifiedby exploring the formation of metalloporphyrins catalyzed by acetic acid. Kinetics studies suggested that thefluctuations of reaction rate indicated the formation of metalloporphyrin was step-wise
