The hydrophobic adsorption film gradually grows and passivates on jamesonite from -78 mV to 42 2 mV.The electrode process of jamesonite at 522 mV is quite controlled by the reaction that is depended on ion diffusion.When the electrode potential is over 622 mV,the hydrophilicity on jamesonite becomes strong due to covering an amount of PbSO4 from the electrochemical reactions.
