研究了25、55和85°C下水、饱和NaCl溶液和Q-盐水中钍、铀、镎、钚和镅在水滑石、雪硅钙石、钙钒石和水化硅酸钙凝胶上的吸附行为。形态也进行了研究。所获得的数据将满足Freundlich的等温线，如果作为一个参数，但即使朗缪尔的等温线将是有效的，如果考虑到各种离子物种的离子浓度。一个理论参数，它允许各种胶凝材料的溶液能力进行比较，相对于相关的离子物种存在。
The sorption of thorium, uranium, neptunium, plutonium and americium on hydrotalcite, tobermorite, ettringite and calcium silicate hydrate gel were investigated in water, saturated NaCl solution and Q-brine at 25, 55 and 85°C. Speciation was also studied.The data obtained will fulfil Freundlich's isotherm if the ion constituent is taken as a parameter but even Langmuir's isotherm will be valid if the ionic concentration of the various ionic species is taken into account.A theoretical parameter was found which permits the solution capability of the various cementitious materials to be compared with respect to the relevant ionic species present.
