摘要
以蚕沙为原料,对从蚕沙中提制叶酸的方法进行研究,并分析检测所得到的蚕沙叶酸。通过考察提取叶酸过程中吸附剂、吸附温度、解吸剂等因素的影响。结果表明:以活性炭为吸附剂,吸附温度为70℃,解吸剂以3%的氨水-70%乙醇溶液最佳,叶酸产率为0.16%,蚕沙叶酸的产品质量达到国家标准GB7302-1987。
A research of extracting folic acid from silkworm droppings, this study investigate the impact of factors such as the adsorbents, adsorption temperature and desorption agents through the extraction of folic acid. The results show the optimum conditions were as follows： activated carbon as adsorbent, the adsorption temperature is 50℃, mixed 3% ammonia and 70% ethanol solution as desorption agents. The quality of folic acid reaches the national standard GB7302-1987. The product ration of folic acid is 0.16%.
