| 摘要 |
A method for removal of contaminants from marine and vegetable oils wherein a first absorbent comprising chitosan and a second absorbent comprising activated carbon are mixed into the oil until a homogenous suspension is obtained, let this oil suspension rest until most of the formed precipitations have sedimented, separating said sediment from the oil and perform purification of the oil phase. The step of purification of the oil phase which contains microparticles of chitosan with absorbed substances can be performed by exposing the oil phase to an electric field generated with direct current between a cathode and an anode in the reaction vessel to obtain that the suspended substances are deposited on the anode. The invention also relates to such oil purified by the invented method. |
