Removal of Cr(VI) from Aqueous Environments Using Micelle-Clay Adsorption

Table 2

Comparison between the efficiencies of different low cost adsorbents towards removal of Cr(VI) at pH = 6 and temperature = 25.0 ± 0.2°C.

Adsorbents		Adsorption capacity of Cr(VI) mg g^−1	Removal%
(1)	Bagasse [21]	0.0005	30
(2)	Fly ash [21]	0.001	25
(3)	As received CSC [22]	2.2	55
(4)	CSC coated with chitosan [22]	3.65	57
(5)	Micelle-clay complex; (this work)	9.43	86
