Fe3O4-modified sewage sludge biochar for U(VI) removal from aqueous solution: performance and mechanism
Sewage sludge-derived biochar (SSB) was prepared at 600 °C pyrolysis temperature and modified by co-precipitation with Fe 3 O 4 to obtain Fe 3 O 4 @SSB. The adsorption process of U(VI) onto the Fe 3 O 4 @SSB was accurately described by the pseudo-second order and Langmuir isotherm model. The maximum...
