摘要
本文叙述了用物理法及化学法对山苍子核油的脱色试验。物理法以活性炭和活性白土为吸附剂;化学法以H_2O_2为脱色剂。比较了不同剂量、不同脱色剂对脱色效果的影响。并且进行了混合脱色方法的试验,比较了不同中间处理方法、不同投放顺序、不同投量对脱色效果的影响。实验中,以400～900nm区间的波谱吸收曲线对脱色效果进行表征。
In this paper,the physical and chemical methods for the decolourization of Litsea cubeba kernel oil are discribed. Activated carbon and activated clay were used as physical adsorbent and hydrogen peroxide(H2O2) was used as a chemical decolourizer. Effects of kind,dosage and feeding order of decolourizer as well as methods of intermediate treatments of oil on decolourizing efficiency characterized by transmission spectra (400～900nm) were compared.
