Abstract

The adsorption of barium ions on barium titanate in an aqueous solution was studied by
means of batch technique as a function of Ba(II) concentration, temperature and
solution pH using Ba-140 as radiotracer. The results show that adsorption is essentially
complete in ca 180min and the steady state values of adsorption at various
concentrations agree well with the classical Freundlich isotherm and follow first order
kinetics. The pH and temperature of the solution markedly affect the extent of
adsorption. Exposure of the activated barium titanate adsorbent to neutrons and γ
irradiation from a (Ra-Be) neutrons source having an integral flux of 3.85x106
neutrons/cm2 / sec and associated with a nominal γ does of Ca 172 rads/h, affects its
adsorption capacity markedly.
