Biography

Linbo Qian, male, he received his doctor's degree in Environmental Science from Zhejiang University in 2014. He is now an associate professor and master's supervisor of Institute of soil science, Chinese Academy of Sciences. He focused on new materials and modulating mechanism for soil and groundwater remediation, and has made some innovative achievements: (1) The structure-activity relationship between the structure of different functional groups of biochar and metal immobilization was identified. It is revealed that the alkaline functional group changes the metal form, and the organic oxygen-containing functional group and the silicon oxygen functional group dominate the metal adsorption. A new theory of biochar multipoint for metal immobilization was proposed; (2) A new method for simulating the decomposition and aging of biochar in soil and groundwater was established. The mechanism of the reduction of hexavalent chromium by phenolic functional group and the accumulation of cadmium by carboxylic acid functional groups formed by aging was revealed. This work further advances our knowledge for practical application; (3) It is clear that the silica functional group is the main regulatory factor for the removal of Cr (VI) and chlorinated hydrocarbon by biochar and nano zero valent iron. The first demonstration project of biochar-nano zero valent iron for remediation of chlorinated hydrocarbon contaminated groundwater has been successful implemented. This work promotes the engineering application of biochar-nano zero valent iron. He has published 35 SCI papers, four of which were selected as highly cited papers of ESI, and his publications have been other-cited in SCI papers over 1000 times.
