The abundance of clay in the Merauke district has not been utilized optimally. This is due to a lack research and information about these clays. Clay one natural minerals from silica group whose particle size less than two micrometers many uses, including basic materials for manufacture ceramics, paper-making materials, adsorbents, assisting drilling, bleaching CPO. In this study, characterizat...

The chlorophyll content of canola oil, especially when extracted from frost-damaged seed is high, and results in dull, dark brown oil unless very large quantities of bleaching clay are used. We found that treatment with phosphoric acid, under vacuum in the absence of moisture precipitates most of the chlorophyll. At 140°C 2400 mg/L phosphoric acid precipitated 98 % of the chlorophyll in canola ...

This paper carried out experimental study, through extraction and characterization of both crude and refined castor oil. Normal hexane was used as solvent for the extraction process. The oil produced was refined through degumming, neutralization and bleaching process using local adsorbent (activated clay). The characterization analysis revealed that tested parameters, which include specific gra...
