摘要：
The kinetic laws of the dissolution of manganese(IV) oxide using citric acid are studied as functions of the temperature and pH of a solution and the concentration of citric acid. The following kinetic parameters of the dissolution are calculated: the reaction rate, the reaction order with respect to citrate ions (n = 0.6), and the activation energy (Ea = 47.4 kJ/mol). The optimum conditions favoring an increase in the leaching intensity and economical consumption of the reactants are experimentally determined.
