Abstract:
1. A chemical combination (C′), between an active solid phase which is covalently bound to the surface of an inert solid phase, wherein the solid active phase comprising a hydrotalcite active solid phase of the formula (IV): wherein A n− is mainly a silicate or a polysilicate anion; 0≦x≦0.3; 0≦y≦0.9; 0≦p≦0.9; 0≦m≦0.5; 0≦k≦10; x+y>0; 0.5≦y+p≦0.9; x+y+p+m=1; and z is the total electrical charge of the cationic element, and wherein the inert solid phase is a hydrotalcite inert solid phase of the formula (V): wherein A n′− is mainly a silicate or a polysilicate anion; 0≦2−2a≦p0.9; 0≦2a−m≦0.5; 0≦k′≦10; p+m=1; and z′ is the total electrical charge of the cationic element.
