摘要： The present invention relates to an adsorbent for treating an oil comprising a chlorophyll derivative. In particular, the present disclosure relates to an improved silica gel adsorbent for removing impurities, including chlorophyll derivatives and/or trace metals, from an oil, in particular triacylglycerol-based oils. The adsorbent comprises a silica gel treated with an alkali earth metal oxide, such as magnesium oxide, and has a pH of about 7 or greater and a water content of about 3 wt % or greater.
