摘要: 作为一种阴离子聚电解质，海藻酸钠在溶液中的状态易受电解质的影响。通过测定表面张力、荧光光谱和黏度，研究了非离子表面活性剂吐温20与海藻酸钠的相互作用，以及NaCl对该相互作用的影响。结果表明：吐温20-海藻酸钠复合溶液的表面张力在cmc之前高于不添加海藻酸钠的吐温20溶液，海藻酸钠的质量分数越大，表面张力升高越多；加入NaCl溶液后，吐温20-海藻酸钠-NaCl复合溶液的表面张力下降；较高质量分数（0.10%）的海藻酸钠会使吐温20-海藻酸钠复合溶液的I₁/I₃下降；在cpc之前加入NaCl溶液，吐温20-海藻酸钠-NaCl复合溶液的I₁/I₃升高；在吐温20浓度大于cmc^*时，吐温20-海藻酸钠复合溶液的黏度略微降低；在吐温20达到一定浓度后，NaCl会促使复合溶液的黏度略微升高。

Abstract: As an anionic polyelectrolyte, the behavior of sodium alginate solution was easy to be affected by electrolyte. The interaction between non-ionic surfactant Tween 20 and sodium alginate and the effect of NaCl on the interaction were studied by surface tension, fluorescence spectrum and viscosity measurements. The results showed that the surface tension of Tween 20-sodium alginate complexes was higher than that without sodium alginate before cmc. The higher the mass fraction of sodium alginate, the higher the surface tension. The surface tension of Tween 20-sodium alginate-NaCl complexes decreased in the presence of NaCl. The I₁/I₃ of Tween 20-sodium alginate complexes decreased when the concentration of sodium alginate increased. Before cpc, I₁/I₃ of Tween 20-sodium alginate-NaCl complexes increased in the presence of NaCl. When the concentration of Tween 20 was higher than cmc^*, the viscosity of Tween 20-sodium alginate complexes decreased slightly. The viscosity of Tween 20-alginate complexes increased slightly in the presence of NaCl when Tween 20 reached a certain concentration.
