菜籽饼制备黄腐酸关键参数研究
Study on Key Parameters of Biochemical Fulvic Acid Preparation from Rapeseed Cake
摘要
Abstract
Sulfuric acid digestion is an effective method to decompose cellulose,hemicellulose and lignin into monosaccharides or disaccharides.The experiment was designed as a 3-factor completely randomized experimental design with response surface method was used to investigate the effects of sulfuric acid mass fraction,acid digestion temperature and acid digestion time on the content of fulvic acid using rapeseed cake as the raw material for acid digestion,and to screen the optimal parameters for the preparation of fulvic acid from rapeseed cake.The results showed that the mass fraction of sulfuric acid,acid digestion temperature and acid digestion time had significant effects on the content of xanthohumic acid.The optimal parameters for the preparation of fulvic acid from rapeseed cake by sulfuric acid digestion were the temperature of 100℃,sulfuric acid mass fraction of 25%and acid digestion time of 0.5 h.The content of fulvic acid prepared from rapeseed cake by sulfuric acid digestion was the highest in this condition,which was 14.17%,nitrogen content was 0.56%,phosphorus content was 0.25%and potassium content was 0.0028%.关键词
