This can be associated with the rapid conversion of AB to B. As the system attains an stable state, evenness decays to its minimum value.
The size of build-up edge tends to increase and attain a stable state with the increase of cutting distance.
The aqueous phosphate concentration increased rapidly with time and achieved a peak value within 1 12 h, and then decreased gradually and attained a stable state after 2160 h dissolution.
The aqueous Pb2+ concentrations increased quickly with time and reached a peak value within 1 12 h, and then decreased gradually and attained a stable state after 720 2160 h dissolution.
For the solids with low XPb (0.00 0.80), the aqueous Pb2+ concentrations increased quickly with time and reached a peak value after 1 12 h dissolution, and then decreased gradually and attained a stable state after 720 2160 h dissolution.
The aqueous Pb2+ concentrations increased rapidly with the dissolution time and achieved a peak value within 240 720 h, and then decreased gradually and attained a stable state after 5040 h dissolution.
Before each potentiodynamic polarization (Tafel) and electrochemical impedance spectroscopy (EIS) measurement, the electrode was immersed in test solution at open circuit potential (OCP) for 10 min to be sufficient to attain a stable state.
Figure 2C shows shift in orientation of the ligand within the catalytic cleft of TACE after attaining a stable state.
Consequently, the sparingly soluble endmember Pb-HAP [Pb5(PO4)3OH] will be gradually enriched in the solid phases, whereas the aqueous solution will become progressively rich in Ca2+ when an equilibrium or a stable state is attained [46].
The processing force is the average value when the cutting process attains a stable stage.
