About
Dr. Guangming Xu is a leading figure in the field of analytical chemistry, with a primary focus on the development of advanced flow injection analysis (FIA) techniques for trace metal determination. His research centers on enhancing the sensitivity and selectivity of atomic absorption spectrometry through innovative on-line sorbent preconcentration methodologies. Dr. Xu’s most notable contribution is his pioneering work on using 1,10-phenanthroline (phen) as a complexing agent for copper determination. His seminal 2000 paper, “Copper determination by flow injection on-line sorbent preconcentration coupled with flame atomic absorption spectrometry using 1,10-phenanthroline,” demonstrated that phen is significantly more stable and selective than traditional agents like sodium-diethyldithiocarbamate (DDTC) and ammonium-pyrrolidinedithiocarbamate (APDC) for on-line preconcentration on RP-C18 material. This work, cited over 10 times, established a more robust and efficient method for trace copper analysis, directly impacting environmental monitoring and quality control. Dr. Xu’s research continues to drive improvements in analytical sensitivity, making him a respected authority in trace element analysis and sample preparation techniques.
