What is the ion exchange mechanism in use?
The capacity of natural and artificial wetlands to adsorb heavy metals is well known. The ion exchange reactions occurring within these wetlands involve the replacement of the hydronium ions contained within the various natural acids produced by partial decay of plant matter. These acids are often collectively referred to as humic acid. The humic acid content of the peat in our harvest area is approximately 28%. The activation process developed by American Peat Technology hardens the granular peat while preserving this ion exchange mechanism.
