Recently, the National Natural Science Foundation of China's regional innovation key project "Research on Phase Equilibrium of New Titanium-based Spinning Ion Screen Composites and Carbonation Systems" led by Professor Deng Tianlong of the Solution Chemistry and Separation Technology Team of the School of Chemical Engineering and Materials was approved. The project number is U21A20299, with a direct funding of 2.60 million yuan. The project aims at how to charge and recover lithium in the lithium sinking mother liquor of salt lakes in our country, and realize the green separation and efficient resource utilization of the lithium sinking mother liquor, which seriously restricts the development of the lithium salt industry in salt lakes. The innovative academic idea of phase equilibrium of carbonation system and its new spinning ion sieve to extract lithium is proposed, and the dynamic model of phase equilibrium of carbonation system is constructed to provide basic data and feasible technical solutions for the common problems involved in the recovery of lithium sinking mother liquor. This is also the second key project of the National Natural Science Foundation of China that Professor Deng Tianlong has chaired in the past 10 years.

At the same time, it was learned from the China Petroleum and Chemical Industry Federation that the "Phase Diagram and Application of Water and Salt System" (Second Edition) edited by Professor Deng Tianlong and others won the second prize of the 2021 China Petroleum and Chemical Industry Excellent Publication Textbook (http://www.cpcif.org.cn/detail/8584430b-e211-4eff-be72-7bdc13ce3313). The textbook is a characteristic textbook for the "Phase Diagram of Water and Salt System" course of two undergraduate majors of chemical engineering and technology and marine resource development technology in our university. It has been selected as the textbook for the 13th Five-Year Plan of China Light Industry (2018) and the first batch of excellent textbooks for ideological and political courses in Tianjin universities (2021). On the basis of inheriting the classics, the textbook introduces new achievements such as calorimetric technology and solubility characteristic database, which are used by undergraduates and graduate students in related majors in many domestic universities, laying the foundation for the training of talents in the field of salt lakes and salt industry

The solution chemistry and separation technology team led by Professor Deng Tianlong focuses on the frontiers of comprehensive utilization of marine brine resources in our country, conducts research on scientific issues and key technologies involved in the separation and extraction of lithium, potassium, boron, rubidium and cesium resources in brine, and has presided over 2 key projects of the National Natural Science Foundation of China, 13 general projects, and 5 youth fund projects; published academic monographs such as "Introduction to Salt Lake Science" (2017) and "Metastable Phase Equilibrium and Phase Diagram of Salt Lake Brine System in Qaidam Basin" (2018) in Science Press; published 8 academic papers in the industry-recognized international top journals Chemical Engineering Journal, Journal of Hazardous Materials, etc., authorized 2 PCT international patents, and authorized 26 national invention patents; won the first national doctorate Seven provincial and ministerial awards, including the Winning Award (2021), the Second Prize of Tianjin Natural Science (2020), and the Second Prize of Tianjin Scientific and Technological Progress Achievement (2019), have been awarded in the Post-Innovation and Entrepreneurship Competition. These achievements have not only promoted the discipline development and doctoral program construction of chemical engineering and technology in our university, but also inspired the scientific and technological workers of sea brine chemical industry to carry forward the fine tradition, strengthen innovation and self-confidence, and focus on conquering key core technologies, so as to contribute to the continuous realization of a scientific and technological powerhouse.
