A simple plant nutrient solution purification method for effective removal of trace metals using controlled pore glass-8-hydroxyquinoline chelation column chromatography.

Abstract

Column chelation chromatography on controlled pore glass-8-hydroxyquinoline was demonstrated to be a very efficient method for removing trace metal contaminants from concentrated macronutrient salt solutions used to prepare nutrient media. By using (63)Ni and (65)Zn radio-isotopes as tracers, controlled pore glass-8-hydroxyquinoline column packings were… (More)
