| 摘 要： | The present paper describes the complex reaction of α, β,γ, δ-tetra-(2-chlorophenyl} porphyrin with platinum in the presence of the mixture surfactant, sodium dodecylbenzene sulfonate and OP, and a new highly sensitive method for spectrophotometric determination of micro amounts of platinum. Beer's Law was obeyed when the concentration of platinum was in the range of 0?.2μg/25ml. The molar absorptivity was found to be 3.1×106 L mol-1 cm-1 at 417nm.
