Abstract

Abstract: Macroporous silica gels of average pore size of 4 × 10²～1 × 10³ nm were prepared from silica gels of an average pore size of 20～30 nm by calcination. The obtained products have pore volumes of 0.8 mL/g and porosity of more than 0.65. Tests have shown that such macroporous silica gels can be used in GPC for the separation of polyacrylamide with M_w < 1.5 × 10⁷.

Key words: macroporous silica gel, NaCl, LiCl, KNO₃, preparation
