摘要
实验测定和分析了我国东部地质和地理条件相差悬殊的 1 1条主要河流的 1 1个表层沉积物样品 (<63μm)的比表面、表面位、表面电荷、表面电位和表面酸度常数 ,研究了地域差异 ,比较了天然沉积物与纯矿物表面性质的差异 ,并讨论了天然水体沉积物表面性质与主要地球化学性质之间的相关性 .
geographically and hydrologically diverse sediment samples were collected from 11 rivers in eastern China.Sediment surface properties (specific surface area,surface site densities,surface charges,surface potentials and surface acidity constants) of all samples (<63?μm) were determined and calculated.Surface properties of natural sediments vs pure solids were compared.Relations of surface properties to the geo\|chemical properties of the natural sediments were discussed.
