In the present study, experiments have been performed to investigate the effects of the type of adsorbent, pH, and ionic strength on the adsorption of nutrients (nitrate and phosphate in artificial solution) onto the dredged sediment from a coastal fishery. In addition, this study aims to evaluate the possibility of removing the nutrients from the water using the dredged sediment. In the adsorption experiments of the nutrients, the reactions were completed within 10 minutes using ${NO_3}^-$-N($100{mu}M$, 10mM) and ${PO_4}^{3-}$-P($100{mu}M$, 10mM). In the steady state, 61% and 77% of the initial amounts were removed respectively for $100{mu}M$ ${NO_3}^-$-N and $100{mu}M$ ${PO_4}^{3-}$-P. The thermal treatment of the dredged sediment at $900^{circ}C$ was not helpful to increase the removal efficiencies of the nutrients. Additives such as CaO and MgO dropped the removal efficiency of ${NO_3}^-$ to 0%, but increased that of ${PO_4}^{3-}$ up to 98%. Adsorption isotherms of ${NO_3}^-$ and ${PO_4}^{3-}$ could be explained by the Freundlich equation ($R^2$>0.99). The adsorption reaction was little influenced by the pH and ionic strength. Based on the results showing short reaction time and considerably high removal efficiencies of the nutrients, it is proposed to apply the dredged sediment from a coastal fishery to removing nutrients such as nitrate and phosphate in the water.
