We focus on the Au nanoparticle, which is fabricated by solution plasma method, as the adsorbent with high density and high efficiency of Cs in solution. To remove the Cs from the solution, we attempt two methods, which are the Cs adsorption on the Au nanoparticle surface and the interaction between the Cs and the L-cysteine on Au nanoparticle. Judging from the results of SR-XPS for the sample at the latter method, we suggest the interaction between the Cs and the COOH group of L-cysteine on Au nanoparticle.
