Zeolite chemical properties of three Iranian natural zeolites
Zeolite	SiO₂	Al₂O₃	CaO	K₂O	Na₂O	Fe₂O₃	MgO	TiO₂	MnO	P₂O₅	LOI	CEC
Semnan	66.5	11.8	3.1	2.1	2	1.3	0.8	0.3	0.04	0.01	12	100
Miyaneh	65	12.2	2.3	3	1.8	1.5	0.1	0.03	0.04	0.01	12	110
Mashhad	68.04	10.14	0.97	1.15	4.31	2.04	1.03	0.31	0.01	0.04	1.94	150

These zeolites were extracted from Miyaneh, Mashhad and Semnan (Afrand Touska Company, Tehran, Iran in 2007). CEC, Cation exchange capacity; LOI, Loss of ignition.
