Summary of the TGA analysis of zeolites.

Zeolite	Observations (%)			References
	Percentage loss (%)	Temperature	Interpretation
Faujasite-type zeolite	1.43	110°C	Surface water loss	[232]
	3.73	200°C	Internal water desorption
Nanoclinoptilolite	2	—	Surfactant adsorption into sample	[233]
Nax-zeolite	26	200°C	Physisorbed water molecules	[231]
Needle-like nanozeolite	14	100–175°	Zeolitic water	[171]
