Abstrak/Abstract The batch adsorption process of Sr (II) ions from the radioactive liquid waste of Sr(NO3)2 using fly ash of Kelud mountain eruptions have been conducted. Liquid radioactive waste of Sr(NO3)2was simulated with88Sr(NO3)2solutions. Effects of adsorbent weights, initial concentrations, and 88Sr(NO3)2 liquid waste temperature on adsorption efficiency were investigated. Concentrations of 88Sr(NO3)2 solution were measured by atomic absorption spectrometry (AAS). Experimental results showed that increasing adsorbent weight enhanced adsorption efficiency by up to 79.82%. However, further raising the adsorbent weight reduced the adsorption efficiency. An increase in initial concentrations of 88Sr(NO3)2 solution diminished adsorption efficiency of 81.35% to 23.54%, though it can be augmented the amount of adsorbed Sr (II) ions per gram of adsorbent of 0.01 mg/g to 0.34 mg/g. Temperature increments of 25 deg C to 60 deg C enhanced the adsorption efficiency from 79.82% to 83.91%, which indicated that the adsorption process occurred endothermically.
