The waste is a solution of Hydrochloric acid and hydrogen peroxide that I used to leach the Rh deposited on a solid Rhodium/CeO2 catalys. It should contain very smalls ammounts of rhodium. Even less than 0.1%. There are seven 24mL glass vials containing the solutions. However, the volume of solution in most of the vials is somewhat around 12 mL.
