Purpose This research aimed to study the adsorption of ammonium and nitrate by simply modifying the surface of the rice husk using slow pyrolysis and surfactants modifcation. Methods Rice husk biochar was prepared by slowly pyrolyzing at 500 °C, 2 h. The rice husk and its biochar were modifed by cetyltrimethylammonium bromide or sodium dodecylbenzenesulfonate. FTIR, BET […]
