Abstract
The effect of seawater to nuclear waste stream was being investigated. This is considered to be important after the Fukushima tragedy. Natural clinoptilolite was selected due to radioactive resistance, which has irregular shapes and an average particle size of 30 µm, considered a fine particle in this paper. A good performance for both uptake and percent adsorbed of cesium using fine natural clinoptilolite during adsorption kinetics and adsorption equilibrium experiments, where the results were obtained from an an Atomic Absorption Spectrophotometer (AAS) machine with the optimum range at 0.04 - 4000 ppm of cesium concentration. PSO and Langmuir models are the best fit model for adsorption kinetics and equilibrium results, respectively. There is a smaller decrease during cesium adsorption in the saline simulant experiment, mainly due to the competition of potassium and cesium ions. After all, fine natural clinoptilolite could be a good candidate as a natural adsorbent for cesium ions.
