Title: Status of KamLAND-Zen and purification methods

Abstract content KamLAND-Zen experiment was started data taking from October 2011 to search for neutrino less double beta decay. The Mini-balloon filled with 136Xe loaded liquid scintillator was installed in the KamLAND detector. From the first result of KamLAND-Zen, there was the BG peak at 2.6 MeV region. As a result of data analysis, it was found that 110mAg was the BG candidate. The purification system of xenon and liquid scintillator were developed to remove the 110mAg BG. 136Xe gas was collected from the liquid scintillator in the Mini-balloon to purify 136Xe gas and liquid scintillator, respectively. In addition, 136Xe gas was purified using SASE getter just before dissolving 136Xe into liquid scintillator. The 2nd phase of KamLAND-Zen was started in 2013. I will report the status of KamLAND-Zen and purification methods.
