| titleOfInvention | Electric field and flow field coupling regulation nanofiltration separation method of glucosamine |
| abstract | The invention relates to an electric field and flow field coupling regulation nanofiltration separation method of glucosamine, which is characterized in that a mixture of glucosamine hydrochloride or sulfate to be separated and N-acetylglucosamine in any proportion is prepared into an aqueous solution with the mass percentage concentration of 1-40 percent, the nanofiltration separation is carried out by adopting an electric field and flow field coupling regulation strategy, and the nanofiltration separation conditions are as follows: the membrane material is charged or electrically neutral, the outer side and the core side of the membrane are provided with adjustable and reversible electrodes, and the electrodes at two ends can be connected with direct current or alternating current; the operating pressure range is controlled to be 1 bar-45 bar, the membrane surface flow rate is controlled to be 1 m/s-10 m/s, the solution temperature is controlled to be 1-55 ℃, and the solution pH is controlled to be 1-9. The method has the advantages of high separation efficiency, good economy, simple operation, environmental friendliness and the like. |
