摘要
A silica based solid material is claimed, which is modified on its surface with organosilicon compounds of formula ((RO)ySiR1-SO3-)xM(power x+) (I) and (RO)ySi-R2-SH (II). R1, R2 = independently 1-12 C alkylene, 5-8 C cycloalkylene or units of formula (IIIa) or (IIIb); m, n = 0-6; M+ = H+, NH4+ or a metal ion with a valency of 1-4; H+ provides at least 5% of the ion exchange capacity of (I); y = 1-3; and R = independently H, CH3, CH2CH3 or propyl.
