|a Excessive ammonium and phosphate in aquatic settings may produce major eutrophication. Adsorbents can be used to reduce the eutrophication of natural water bodies. In this study, a sustainable and efficient ceramic adsorbent (sludge/biomass ash ceramsite [SBC]) was prepared by using sludge and biomass ash with a weight ratio of 1:1; the sintering parameters were 1070°C for 15 min. The NH4 + -N and P adsorption capabilities were improved by utilizing 1 mol L-1 NaOH and 1.6 mol L-1 La(NO3 )3 ·6H2 O for modification. When the pH and duration were 7 and 1440 min, respectively, the maximum bending capacity of ammonia nitrogen and phosphorus was 3.2 and 2.1 mg g-1 at 308 K. The pseudo-second-order kinetic model better describes the adsorption dynamics of NH4 + -N and P, whereas the Langmuir model better describes the adsorption isotherm models of NH4 + -N and P. The adsorption mechanism of SBC-NaOH on NH4 + -N is ion exchange between Na+ and NH4 + , whereas the adsorption mechanism of SBC-La on phosphorus is ion exchange and La3+ adsorption. SBC combines efficient wastewater purification with the reuse of solid waste. The findings gave rise to the possibility of recycling ceramics as a plant fertilizer with a delayed release in the future. PRACTITIONER POINTS: New ceramsite was made from sludge and biomass ash. NH4 + -N (3.2 mg g-1 ) and P (2.1 mg g-1 ) were effectively adsorbed by ceramsite. The mechanism of NH4 + -N and P adsorption by ceramsite was studied. Absorbed ceramsite can be used as slow-release fertilizer in plant cultivation
