Adsorption of Trace Quantity ~(241)Am on Glass

The kinetic feature of Am(Ⅲ) adsorption on the surface of glass and the effect of pH on(Am(Ⅲ)) adsorption are studied through using tiny glass balls to simulate the container walls.The results show that when pH value of the solution is 2.04,the film diffusion is a rate-controlled step during the adsorbing process,which belongs to Lagergren first-order kinetic equation.The effect of pH on(Am(Ⅲ)) adsorption is notable.When pH=2~6,the Am(Ⅲ) adsorption on glass is increased with increasing pH,but decreased at pH=6~9.After that,the Am(Ⅲ) adsorption is increased by degrees.
