Abstract

Adsorption of Th4+ on peat by batch method was studied.Effects of solution pH value,ionic strength and Th4+ concentration on adsorption were examined.The results showed that adsorption of Th4+ on peat was strongly affected by pH values and weakly depended on ionic strength.The kinetic process of adsorption could be described by the Langmuir equation excellently.Adorption of Th4+ was mainly dominated by surface complexation.
