| Abstract: | The species distribution of aluminum and kinetics parameters have been investigated by analysis on the kinetics process of Al Ferron complex colorimetric and by true calculation of the three species.The results show that initial Al concentration and temperature affect the rate constant( k b)of Al and Ferron while basicity,mixing intensity and base injection rate affect a little.Basicity,initial Al concentration affect the species distribution evidently,mixing intensity,temperature and base injection rate also have effect on it. |
