石墨烯吸附材料结构性质解析及其在菜籽油脱色中的应用
Structural and Performance Analysis of Graphene Adsorption Materials and Their Application in Rapeseed Oil Decolorization
摘要
Abstract
To overcome the shortcomings of activated bleaching clay in the decolorization of edible oil industry,such as high operating temperature,large residual oil ratio,and difficulty in the disposal of waste bleaching clay,this work developed the super-strong adsorbent material,graphene,as a new type of adsorbent for the decolorization of rapeseed oil.Graphene nanoplatelets(GNP)and graphene oxide(GO)were characterized by scanning electron microscope.Fourier infrared spectrometer and Raman spectrometer,etc After clarifying the structural characteristics of graphene,they were used for the decolorization of rapeseed oil,and the effects of graphene species,addition amount,pressure,temperature,and reaction time on the decolorization of rapeseed oil were investigated.The results showed that GNP was more effective in rapeseed oil decolorization compared with GO and exhibited unique adsorption properties for chlorophyll in oil at low temperature(45℃).The one-factor results showed that GNP could remove 80.6%of chlorophyll in oil under the optimized conditions of GNP addition of 2.0%,temperature of 45℃and adsorption time of 5 min.GNP as adsorbent for oil decolorization has the advantages of low reaction temperature and short adsorption time,which could have the potential application prospects in low temperature moderate processing of oils and fats.关键词
