Underivatized glass and silica

Rinaudo and co-workers studied the elution of simple electrolytes on porous silica (Spherosil) (24,25). They found that the elution volume of NaN03 in 

The preceding effects can be attributed to repulsion of the anion (N03 or Cl ) from the anionic surface of the pore of the silica they all diminish when the reciprocal Debye length, given by
