The fluorimetric determination of mercury ions with 5,10,15,20-tetra(p-sulfonatophenyl)porphyrin in aqueous solutions and in porphyrin doped sol-gel films was investigated. Optimization of complexation conditions such as buffer components, pH range and temperature resulted in a method which enabled
