| 摘 要： | 通过测定吸附后人体血清的成分，并利用红外光谱研究了几种矿物粉尘对血清中物质的吸附作用，结果表明，矿物粉尘对血清中物质的吸附具有选择性，主要是吸附了血清中的蛋白质和脂类等生物大分子。不同矿物吸附生物大分子的选择性不同，这主要与矿物的结构和表面海性等因素有关。红外光谱研究表明，吸附机理主要是物理吸附，可能也存在化学吸附。另一方面，矿物粉尘在血清中发生了一定程度的阳离子交换和溶解作用。

| Abstract: | The adsorption of substances in human serum on mineral dusts was studied by measuring the composition of the serum after the adsorption and using infrared spectra. The results suggest that the adsorption of substances in human serum on mineral dusts is selective and that the adsorpted substances are mostly biological macromolecules in the serum, such as protein and lipids. Infrared spectra have shown that the adsorption mechanism is mainly physical adsorption and that there is possibly chemical adsorption. The adsorption selectivity of biological macromolecules on varying minerals in the serum is mainly related to the structure and surface activity of the minerals. On the other hand, the cationic exchange and dissolution of mineral dusts occur in the human serum to some extent. |
