大孔树脂孔参数最普通的测定方法是吸附和毛细现象(向孔隙中压汞,吸附和毛细凝聚)为基础。为此,孔的大小便成为决定因素,用电子显微镜方法来观察,只能定性了解;用低温氮物理吸附法(毛细管凝聚法)亦只适用于测定半径为10～300的范围,而最小孔隙的测定,则是根据x射线小角散射法获得。压汞法适用范围较宽,从几十埃到一百微米之间。本文介绍用压汞法测定大孔树脂孔参数的简单原理和测定方法。对其实用性和方法的重现性作初步的讨论。
The most common method of determining macroporous resin pore parameters is based on adsorption and capillary phenomena (mercury intrusion into pores, adsorption and capillary condensation). For this reason, the pore size has become the determining factor, the use of electron microscopy to observe, only a qualitative understanding; with low temperature nitrogen adsorption method (capillary condensation method) is only applicable to the determination of the radius of 10 to 300 range, and the smallest pores The determination is based on x-ray small angle scattering method. Mercury pressure wide range of applications, from tens of a hundred to a hundred microns. This article describes the mercury porosimetry determination of pore parameters of the simple principle and determination method. The preliminary discussion of its practicability and method reproducibility.
