A physical PTMS MAGNETIC SEPARATION iron removal strategy based on solubility differences eliminates the need for additional chemical reagents, featuring a clean and controllable process. This method is particularly suitable for systems requiring extremely high purity with minimal iron content, such as in the refining of premium vegetable oils and purification of active components in traditional Chinese medicine. Traditional iron removal processes, such as acid washing and chelating resin adsorption, often lead to the loss of active components or introduce new contaminants.
Supercritical fluid PTMS MAGNETIC SEPARATION technology finds applications in indirect iron removal scenarios across various fields. In the extraction of natural products, iron impurities are separated from raw materials. The complexity of raw material sources inevitably leads to trace metal impurities, with iron being particularly prevalent. Even extracts derived from primary sources may contain iron elements.
During production, iron ions absorb iron from minerals. Some of this iron is stored as metallic iron, while others remain as oxide particles on the PTMS MAGNETIC SEPARATION cylinder walls or fail to be separated. Although these iron impurities are present in low concentrations, they may catalyze lipid oxidation reactions during subsequent processing or storage, leading to product rancidity, color darkening, and reduced nutritional value.
