| Abstract: | In this paper, the concentration and separation of thermal sensitive hyaluronic acid aqueous solution using the new separation technique with decompressing membrane distillation method are described, resulting in that the concentration of original solution reaches 16 times or more and that the residual degree of hyaluronic acid is 80%, by PTFE membrane combination module with an average pore size of 02m. The influences of the cycle time, temperature of original solution and temperature difference etc are explored. Conditions of separation effect are also investigated. |
