Recently, Associate Professor Wang Wei, Professor Cui Fuyi of the School of Municipal and Environmental Engineering and their team achieved new results and progress in the disinfection of drinking water and security with the support of the National Natural Science Foundation of China and the State Key Laboratory of Urban Water Resource and Environment (SKLUWRE). The research result Highly Efficient Phosphate Scavenger Based on Well-Dispersed La(OH)3 Nanorods in Polyacrylonitrile Nanofibers for Nutrient-Starvation Antibacteria was published in the International Journal ACS Nano (ACS Nano, impact factor 12.881). HIT is the first signature unit and the only communication unit.
Preventing drinking water from recontamination by bacteria is an important project of drinking water security. Though many literatures have described the development and application of lots of disinfection materials, most of them use disinfectant to release toxins damaging cells. HIT researchers combining interface chemistry, developed an efficient trapping agent, which could capture ultra-low concentration nutrients in the water. The trapping agent can not only create a stringent phosphate-deficient condition to kill microorganisms in water, but can also capture the nutrients from bacteria to realize green sterilization. It has duel structures. The nanostructure is packaged within the fabric, which can safeguard the stability of structure and efficient capture capabilities. What’s more, it can also efficiently control nano-structure stripping and ion solubility, showing multiple advantages of high efficiency, stability and security. The study has great significance in the production, transmission and storage of drinking water.
Associate Professor Wang Wei is the doctoral supervisor of the School of Municipal and Environmental Engineering and a member of the SKLUWRE. He has worked at HIT as the introducing talent since 2012, and has published more than 40 SCI papers. He is presiding over 10 research projects supported by the National Natural Science Foundation of China and the National Postdoctoral Special funding.
