文摘In a flow injection separation and precon-centration system incorporating a microcolumn,the adsorption behavior(effect of pH,kinetic adsorption capacity)of metal ions Cu^(²+),Cr+,Mn^(²+),Ni2+,La^(³+),Eu^(³+),Ca^(³+),Mo(V)and W(V)on TiO_(2)powder with different crystal structure and particle diameter was studied an d compared.In addition,the mechanism of the adsorption of metal ions on TiO_(2)powder was explored.The results show that crystal structure and particle diameter of the TiO_(2)powder will definitely afect the adsorption capacity of metals on it.
