This investigation made it possible to compare the sorption capacity of mineral and organic sorbents in respect to U(VI). In order to establish the patterns of sorption, natural sorbents with a high content of rock-forming mineral were used: glauconite, diatomite, zeolite, peat, brown and hard coals, shungite. Each sample was characterized using X-ray diffraction, X-ray fluorescence method, scanning electron microscope, XPS spectra, potentiometric acid–base titration and surface area measurement. The partitioning of U(VI) was determined by sequential extraction technique. It was shown that the highest sorption ability and strongest interaction towards U(VI) is common to peat and brown coal.

U(VI) 吸附到天然吸附剂上

该研究使比较矿物和有机吸附剂对 U(VI) 的吸附能力成为可能。为了建立吸附模式，使用了含有大量造岩矿物的天然吸附剂：海绿石、硅藻土、沸石、泥炭、褐煤和硬煤、闪石。使用 X 射线衍射、X 射线荧光法、扫描电子显微镜、XPS 光谱、电位酸碱滴定和表面积测量对每个样品进行表征。U(VI) 的分配是通过顺序提取技术确定的。结果表明，对 U(VI) 的最高吸附能力和最强相互作用是泥炭和褐煤所共有的。
