Ph.D. RESEARCH:
Aluminum, being the most abundant metallic element, is extremely neurotoxic, especially to children. Humic materials can greatly alter mobilization and speciation of aluminum depending on pH. This study focuses on Al-Fulvic Acid complexes using nuclear magnetic resonance at pH 3 to 5, aluminum ion concentration 20 to 150 mg/L and fulvic acid concentrations from 100 to 5000 mg/L. Metal speciation models (MINTEQ & GEOCHEM ) are also incorporated to explore aluminum speciation.
