Welcome to our Analysis and Degradation of Emerging Contaminants Lab in the School of Engineering at Westlake University (Environ-Chem Lab). Established in 2021, we work at the interfaces of analytical chemistry, quantum chemistry, environmental chemistry, environmental engineering, and environmental microbiology and aim to address the following issues regarding emerging contaminants:

  • Environmental occurrence and health impacts
  • Environmental fate in natural and engineered systems 
  • Degradation mechanism and reaction pathways
  • Treatment and remediation technologies

Our research focuses on the analysis, environmental fate, and degradation of emerging contaminants, particularly per- and polyfluoroalkyl substances (PFASs) and fluoro-pharmaceuticals. 

The key subjects include:

  • High throughput quantitative analysis and nontarget analysis

  • Environmental fate and transformation of PFASs

  • Complete degradation techniques of PFASs

  • DFT calculations on reaction mechanisms

  • Dechlorination and defluorination by functionalized nZVI

  • Microbial degradation of emerging contaminants

  • Life cycle assessment (LCA) on remediation techniques

  • Simulations on transport and multi-media distribution

  • Emerging contaminants, PFASs, PPCPs

  • DFT calculations, molecular dynamics

  • Target and nontarget analysis, HRMS

  • Advanced oxidation, advanced reduction

  • In situ remediation, water treatment

  • S-nZVI, groundwater remediation


Our goal is to train our students to think critically, to become experts in lab instruments and theoretical calculations, and to gain soft skills including teamwork, leadership, writing, and oral communications.

The instruments we use regularly include UPLC-MS/MS, UPLC-Orbitrap-HRMS, GC-MS, HPLC, IC, combustion IC, ICP-AES, TOC, NMR, et al. We conduct quantum chemical and molecular dynamics calculations using Gaussian, CP2K, ORCA, et al.
