Researchers  Stanford University Medical Center  other institutions have recently developed a new type of nano-water purification filter paper. This mesoporous ceramic membrane product can effectively filter out heavy metals such as lead  arsenic without using voltage, chemicals  gravity gravity filtration. As well as bacteria  viruses.

Cheng Zhen, an R & D team researcher  associate professor at Stanford University Medical Center, said in an interview with Xinhua News Agency that the core technology of the product is a mesoporous ceramic layer sandwiched between two layers of paper, which is implied in a half A4 size ceramic layer With more than 18 billion nano hooks.

Laboratory studies by institutions such as the University of Hawaii  the Chinese Medical University have shown that this filter paper can quickly filter out bacteria  viruses without using traditional sterilization methods such as chemical drugs  ultraviolet disinfection.

"When bacteria  viruses pass through the filter paper, they will be hooked. Like the principle of an explosion hook used for fishing, their protective film will be destroyed, thus making their DNA (deoxyribonucleic acid) inactive." Cheng Zhen said.

The researchers said that this filter paper can be widely used in ordinary household water filtration, industrial heavy metal wastewater filtration, nuclear pollution wastewater treatment  agricultural irrigation.

The researchers showed the water purification filter paper at the annual meeting of the American Water Quality Association in Denver, Colorado.
