The electrochemical cell glassware (Pine Instrument, USA) and the components were soaked in concentrated sulfuric acid (Millipore Sigma, USA) overnight, followed by a 5–6 times repeat sequence of boiling with DI water followed by DI water replacement after each boil. This procedure is followed ...
Kinetic parameters such as apparent activation energy, pre-exponential factor, order of acid concentration, and Avrami coefficient were calculated and model equations were derived. Apparent activation energy values were calculated for the leaching of MoO3, NiMoO4, Al2O3, and AlPO4 from spent ...
