摘要: 采用聚砜中空纤维膜处理塔拉单宁水提取液,研究了聚砜膜的截留分子质量,跨膜压差、膜面流速以及溶液温度对膜性能和产品质量的影响。结果表明,以截留分子量为10000,跨膜压差0.2 MPa,膜面流速2.0 m/s,40~45℃下对塔拉单宁水提液进行膜分离,可以得到浊度0.5 NTU以下,纯度85%以上的高品质塔拉单宁。

Abstract: Polysulfone membrane was used to treat the solution of tara tannin. The influencs of several factors such as the mole-cular weight cutoff, trans-membrane pressure, flow velocity, and temperature on membrane property and product quality were studied. The experimental results showed that, under the conditions of molecular weight cutoff of 10000, trans-membrane pressure of 0.2 MPa, flow velocity of 2.0 m/s, and temperature of 40-45℃, the tara tannin with turbidity≤0.5 NTU, and purity ≥85% was obtained.

Key words: membrane separation, tara tannin, extraction, polysulfone membrane
