Comparison of Adsorption Capability of Activated Carbon and Metal Doped TiO₂ for Geosmin and 2-MIB Removal from Water

Table 4

Langmuir constant parameters for Geosmin and 2-MIB analysis.

Adsorbate	Adsorbent	Langmuir isotherm parameters
		2-MIB	GAC	0.62	0.80	0.71	0.98
Fe-TiO2	0.64		1.14	0.58	0.99
Pt-TiO2	0.70		1.56	0.56	0.99
Geosmin	GAC	0.64	0.90	0.69	0.98
	Fe-TiO2	0.70	1.35	0.60	0.99
	Pt-TiO2	0.72	1.53	0.57	0.99

Value of interpretation: greater than 1 indicates unfavourable isotherm, equal to 1 means linear isotherm, between 0-1 shows favourable isotherm, and 0 indicates irreversible isotherm.
