Application of the coconut fiber in radioactive liquid waste treatment

An adsorption agent based on chitosan–zeolite composite: environmental and radioactive liquid waste remediation

“…The authors found a lower adsorption capacity (∼8-fold) for 137 Cs (4.66 × 10 −8 mg g −1 ) but higher capacities (∼14-fold) for U (total) (1.96 mg g −1 ) and 241 Am (∼4-fold) (3.94 × 10 −5 mg g −1 ). 65 They used raw and activated coconut fibre to treat a similar waste. In comparison with the NaX–chitosan, regarding 137 Cs, these materials presented much lower adsorption capacities: 4.47 × 10 −8 mg g −1 (raw) and 3.77 × 10 −8 mg g −1 (activated).…”
