摘要:
采用三室离子交换膜渗析法,将甲酸钠与氢氧化钙转化为甲酸钙,为探索一条合成甲酸钙的绿色工艺提供参考依据.实验过程中,以浓度差为推动力使HCOO-与OH-通过阴离子交换膜进行交换,使Ca2+与HCOO-结合生成甲酸钙.考察了甲酸钠初始浓度及膜使用周期对离子交换率的影响.结果表明,甲酸钠的浓度为15 g/L时产物中HCOO-含量最高;在相同的条件下,随着阴膜使用周期的增加膜效率下降,第一次实验中Ca2+最高含量为第四次的1.68倍,HCOO-最高含量为2.13倍.
Abstract:
Calcium formate was recovered from sodium and formate by calcium hydroxide ionexchange membrane dialysis with three campartments to provided reference for a green technology of calcium formate synthesis. It made HCOO- and OH- through the anion exchange membrane under differential concentrations while Ca2+ and HCOO- binding to form calcium formate.The influence of initial concentration of sodium formate and using period of membrane on ion exchange ratio of on was investigated. The results showed that HCOO- content was the highest in products when concentration of sodium formate is 15 g/L. The membrane efficiency decreased as the increase of using period of anionexchange membrane under the same condition. The highest content of Ca2+ and HCOO-of the first experiment is 1.68 times and 2.13 times of the fourth, respectively.
