Research project

Trace metal pre-concentration and speciation in environmental samples. Immobilized and soluble chelating reagents utilized for pre-concentration and matrix replacement purposes. Development of automated systems for process control of enrichment procedures interfaced with graphite furnace techniques, forms an integral part of the research project.
