Description générale

Aluminum potassium sulfate dodecahydrate is an inorganic sulfate salt of aluminum and potassium. Linear growth rates of (100), (111) and (110) faces of its crystals have been investigated.

Application


  • Extraction and characterization of lignin from oil palm biomass via ionic liquid dissolution and non-toxic aluminium potassium sulfate dodecahydrate precipitation processes.: This study explores an environmentally benign method for extracting lignin from oil palm biomass using ionic liquids, followed by the precipitation of lignin using non-toxic aluminium potassium sulfate dodecahydrate. The process is notable for its eco-friendliness and efficiency in lignin recovery, highlighting a potential application in bio-refining technologies (Mohtar et al., 2015).

  • Reduction of house-dust mite allergen concentrations in carpets by aluminium potassium sulfate dodecahydrate (alum).: This research investigates the effectiveness of aluminium potassium sulfate dodecahydrate (alum) in reducing allergen concentrations in household carpets. The study demonstrates alum′s potential as a simple and cost-effective method to significantly decrease allergen levels, thus contributing to improved indoor air quality and reducing allergen-related health issues (Sevki et al., 2006).
