Arsenic is a toxic heavy metal. It has caused serious pollution of groundwater recent years, the treatment of arsenic contamination drinking water becomes a hot research topic. In this paper, the granitization red soil, which is widely distributed in South China, cheap easy to get is used as the adsorption material, studied by adsorption of arsenic removal performance. The results show that after...
This work reports real-time soft-error rate (SER) testing of semiconductor static memories in both altitude and underground environments to separate the component of the SER induced by the cosmic rays (i.e. primarily by atmospheric neutrons) from that caused by on-chip radioactive impurities (alpha-particle emitters). Two European dedicated sites were used to perform long-term real-time measurements...
The extensive clayization of Dexing copper mine is responsible for water and soil pollutions because of the oxidation of sulfide minerals. During the clayization, harmful elements such as As, S, Sb and Pb could be effectively released into the clay and water. Using the abundant spectral information of short wave infrared (SWIR), combining with the spectral absorbed index, SAM (Spectrum Angle Mapper)...
