Methylsulfonylmethane (MSM) is one of the main sources of sulfur for living bodies, but it is hard to obtain as a pure compound. Conventional electrodialysis (CED) is a mature technology that can be used for the separation and purification of biochemical products. In this study, the purification of MSM from mixtures containing salt was performed by CED. The effects of operating conditions such as operation voltage drop, feed MSM concentration, and electrolyte salt concentration on the separation performances were investigated. The results showed that the current efficiency reached 74.0%, and the energy consumption could be 12.3 Wh·L. As for the recovery rate and desalination rate, the highest recovery rate could be 97.4%, and the desalination rate was 98.5%. Based on process energy consumption calculation, the total cost of the whole process was estimated at only 2.34 $·t. Thus, CED is highly efficient and cost-effective for the separation and purification of MSM.
二甲基砜（MSM）是生物体硫的主要来源之一，但难以获得纯化合物。传统电渗析（CED）是一种可用于生化产品分离和纯化的成熟技术。本研究采用CED从含盐混合物中纯化MSM。研究了操作电压降、进料MSM浓度和电解质盐浓度等操作条件对分离性能的影响。结果表明，电流效率达到74.0%，能耗为12.3 Wh·L。至于回收率和脱盐率，最高回收率可达97.4%，脱盐率为98.5%。基于过程能耗计算，整个过程的总成本估计仅为2.34美元·吨。因此，CED用于MSM的分离和纯化具有高效性和成本效益。
