Phosphate (PO43-) and Nitrate (NO3-) are two main nutrients that cause water eutrophication. In the other hand, the presence of PO43-？and NO3-？is needed for plant growth. The aims of this study are to recycle？Spent Coffee Ground (SCG) modified with calcium hydroxide for adsorption PO43-？and NO3-. The optimum adsorption capacity for PO43-？and NO3-？is 36.74 mg/L and 20.21 mg/L, respectively. The Freundlich isotherm model was suitable for PO43-？and NO3-？adsorption. The kinetic model for adsorption was linear using Pseudo-second order. The application of modified SCG after enrichment with PO43-？and NO3-？for plant growth (Raphanus sativus) showed？optimum growth at a dose of 0.3% with value of germination index was 203%.
