Effect of hydrothermal treatment in the presence of salts on the chromatographic properties of silica gel

Some questions on the mechanism of changing of silica sorbents structural characteristics under hydrothermal treatment

“…It is possible to regulate such parameters as pore diameter, pore size distribution (PSD), and specific surface by means of hydrothermal treatment (HT). In spite of the fact that the main works on HT of silica gels were accomplished about 30 years ago, this method is still used for obtaining wide-porous silica gels [1][2][3][4][5][6].…”
