Abstract: Kinetic study on the reaction of waste aluminum powder with hydrochloric acid has been carried out by measuring the volume of released hydrogen gas. The reaction rate is found to be in direct proportion to the 1.5th power of the concentration of HCl solutions in the range of 0.5～3N HCl. The apparent activation energy is 48 kJ/mol H2. The rate equation for the waste aluminum powder as follows: dH2/dt=6.2×102·exp(-5.8×103/t)·W·CHCl1.5(mol/s).
