| Abstract: | With Co(NO3)2.6H2O for nuclide source,clinoptilotite in Xinjiang for adsorbent,kinetic adsorption and desorption effect of clinoptilotite for Co2+ was studied.The relationship between adsorption time,Co2+ initial concentration and the adsorption quantity was discussesed.With pH=6 water in solution,clinoptilotite that saturated adsorption of Co2+ was desorbed.The results showed that the adsorption of clinoptilotite to Co2+ in 2 h can achieve maximum absorption 99.5%.Adsorption curve fits Freundlich isotherm ... |
