Web7 jan. 2015 · It all starts with a swamp on the edge of a , such as a lagoon or a lake. Tectonic activity raises sea levels, covering and killing vegetation. Plant debris accumulates and is buried under layers of mud and sand in a process known as sedimentation. This protects the debris from the air and slows down the decomposition process. WebPeat materials can very easily remove cations from solution and retain them. The humic substances are then considered to determine the binding capacity. The dominating exchange sites of peat compounds are the carboxyl (–COOH) and phenolic hydroxyl (-OH) groups. The ions bind to these by ionic attraction as well as by forming complexes of ...
