生产中的维生素C钠溶液转换成维生素C一般使用大孔阳离子树脂去除Na+,但是在树脂再生过程中,一般使用HCl再生,而HCl再生有成本偏高的劣势,本文是根据工业H2SO4浓度、使用量、成本等综合考虑,来替代HCl再生大孔阳离子树脂,并对树脂的活性、寿命等进行了相关研究。
Production of vitamin C sodium solution into vitamin C macroporous cationic resin commonly used to remove Na +, but in the resin regeneration process, the general use of HCl regeneration, and HCl regeneration has the disadvantage of high cost, this article is based on industrial H2SO4 concentration, the use of Volume, cost and other considerations, to replace the macroporous cation exchange resin HCl, and the resin activity, life expectancy and other related studies.
