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活性等因素有关。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
By measuring the composition of the human serum after adsorption, and using infrared spectroscopy to study the adsorption of several mineral dust on the serum substances, the results show that mineral dust on the adsorption of substances in the serum is selective, mainly adsorption of serum protein And lipids and other biological macromolecules. Different minerals adsorption of biological macromolecules of different selectivity, mainly with the mineral structure and surface activity and other factors. Infrared spectroscopy studies show that the adsorption mechanism is mainly physical adsorption, chemical adsorption may also exist. On the other hand, mineral dust has some degree of cation exchange and dissolution in the serum
