Development of advanced adsorptive separation technology for environmental and biopharmaceutical applications

点击翻译按钮获取中文摘要

Adsorption and chromatography play a critical role in separating and purifying valuable chemical and biochemical products. High cost of operation and low separation capacity remain the major bottlenecks in their implementation to environmental and biopharmaceutical separations. My research in the past several years has focused on developing new sustainable adsorbents and advanced adsorption-based separation processes. Building on the strengths of past research efforts, the proposed research program aims to address the challenging topics of (i) developing new porous polysaccharide-based adsorbents for selective adsorption and recovery of precious metals; and (ii) exploring new techniques for isolation and purification of therapeutic proteins by preparative liquid chromatography.
