Latest Patents
Spigarelli holds a patent for an improved process for preparing a cation exchange material from peat, specifically selected from sphagnum or reed-sedge peat. This patent focuses on enhancing the ion exchange capability of peat. The process begins with drying and grinding the raw peat to a particle size of less than one millimeter. The particulate material is then hydrolyzed in a moderately strong acid solution to separate soluble components. Following this, the hydrolyzed material undergoes reflux in an organic solvent, such as a mixture of 2-propanol and toluene in a 1:2 volume ratio. After removing the residual solvent, the peat is reacted with warm concentrated sulfuric acid and subsequently ground or milled to achieve a desirable particle size.
