Abstract

Abstract: 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 0-1.2μg/25ml. The molar absorptivity was found to be 3.1×10⁶ L mol^-1 cm^-1 at 417nm.

Key words: α,β,γ,δ-Tetra-(2-chlorophenyl) porphyrin, Platinum, Spectrophotometry
