Amine-algae interactions: cation-exchange and possible hydrogen bonding

Results are published from experiments on the sorption of 7 mono-amines, 3 diamines, and 3 amino acids by the alga Vaucheria sp. A new technique was used to measure the strength and extent of sorption, based on the amount of calcium and magnesium displaced. Sorption of amines by algae in acid media...

Description
Summary:Results are published from experiments on the sorption of 7 mono-amines, 3 diamines, and 3 amino acids by the alga Vaucheria sp. A new technique was used to measure the strength and extent of sorption, based on the amount of calcium and magnesium displaced. Sorption of amines by algae in acid media was similar to sorption of metals and could involve ion exchange of protonated amines and sorption of neutral amines, probably through hydrogen bonding. Some environmental implications of the findings are indicated.
