Sinochem New Network News “A third-generation bio-ceramic technology that can quickly and efficiently adsorb and filter nuclear polluted wastewater has been successfully developed in China. It can be used not only to prevent the spread of radioactive substances iodine-131 and other radioactive iodine isotopes, but also It is widely used in nuclear accident emergency, nuclear waste water treatment, nuclear facility protection, medical radioactive waste water treatment, etc.†On April 20, the Luohe Municipal Government released the nuclear waste water treatment technology sponsored by Zhengzhou in the news conference of the catalytic earthenware project. This news. This major high-tech achievement will be officially put into production in Henan Tianyuan Environmental Protection Hi-Tech Co., Ltd. in the near future.
This domestic first new technology was successfully developed by an interdisciplinary team consisting of environmental science, chemistry, biology, and physics. Environmental scientist Dong Liangjie introduced: "This new material is called catalytic ceramics, but it is not a ceramic in the ordinary sense, it is also different from the traditional adsorption material." Particles made using this new technology is a selective function The high-efficiency adsorption material can quickly, simply, and efficiently adsorb and immobilize radioactive substances such as iodine-131 and iodine-125 radioactive ions. The core of this technology is to achieve orientation, selective adsorption, and immobilization on the material.
At the press conference, Dr. Zhang Zhiyong, deputy director of the Nuclear Analytical Technology Key Laboratory of the Institute of High Energy Physics, Chinese Academy of Sciences, announced to the media that the China Atomic Energy Research Institute’s test report on April 14 showed that 10 grams of catalytic bio-ceramic particles were soaked in Radioactive iodine-131 in 12640 BK/liter of nuclear waste water can adsorb and immobilize up to 99.97% of radioactive material iodine-131 in 20 minutes. China Atomic Energy Research Institute researchers and researchers said: "This material is highly shocking to the adsorption efficiency of iodine-131."
The reporter learned that the first generation of bio-pottery technology was successfully developed at the University of Hawaii in the United States in 2004 and was used in industrial water treatment applications in the United States; the second-generation bio-ceramic technology was successfully developed in 2008 and obtained Chinese patents; the third generation of bio-ceramics The technology was invented in China by Dong Liangjie, an environmental scientist in China, and applied for a patent for invention in that year. On March 11th, since the nuclear disaster in Japan, the interdisciplinary R&D team led by Dong Liangjie has adjusted, updated, and tested on the basis of the original technology accumulation. Finally, radioactive iodine isotopes such as iodine-131 and iodine-125 have been A major breakthrough has been made in directional adsorption and fixation.
