6. Impact of weathering solution composition on weathering kinetics
The altering solutions considered here are typically "natural" waters (seawater, geological site waters). The main elements in solution identified as playing an important role in glass weathering are Si, Al, Ca, Mg, P :
under initial velocity conditions, the presence of cations in solution (Li, Na, K, Ca, Fe, Zn, Ni, Cr and Nd) or anions (Cl – ,
