AN AUTOCATALYTIC CONSTANT SENSITIVITY DETECTION SYSTEM FOR CATALYSTS AND INFECTORS

Mathematical model calculation shows that the shape of the reactant concentration-time curves of autocatalytic reaction system at their inflection time is similar to each other even for different initial concentrations of catalysts. It should be of great value as a theoretically infinite sensitivity detection system for catalysts or its infectors. This model has been demonstrated by the use of oxidative destruction of cobalt complexes of 2,4-(2-pyridylazo)benzenediolate and phthalocyaninetetrasulfonate with peroxomonosulfate in aqueous phosphate buffer solution (pH 7) at 25 degrees C.
