Determination of contaminants adsorption expressed as percentage of the initial concentration.

Sorbent	Cu^2+	Cd^2+	Eosin y	Rose bengal	Fluorescein	Methylene blue	Phosphate
SSO	20	13	40	60	77	3	30
SSO-Gt	30	26	80	81	89	5	60
SSO-MMT	34	32	40	60	80	16	20

Initial concentration of contaminants: Cu²⁺: 3.0 mg/L; Cd²⁺: 0.8 mg/L; eosin y: 2.8 mg/L; rose bengal: 3.6 mg/L; fluorescein: 9.0 mg/L; methylene blue: 2.6 mg/L; phosphate: 2.3 mg/L.
Sorbent mass: 0.30 g in 5 mL of contaminant solution.
