A kinetic study on the influence of the parameters in the determination of inorganic phosphate by the molybdenum blue reaction.


Parameters which influence the initial rate of formation of phosphomolybdenum blue from phosphate, molybdate, polyvinylpyrrolidone and o-phenylenediamine were investigated. From kinetic data it is concluded that polyvinylpyrrolidone not only acts as a protective colloid, but that it takes part in the reaction and a reaction mechanism is proposed dealing… (More)
