摘要
利用核磁共振(1H-NMR)测定了不同海藻酸钠的M/G值,经湿法纺丝法制备了海藻纤维,并研究了M/G值、海藻酸钠用量及凝固浴用量和凝固时间对海藻纤维吸附性能的影响.结果表明,海藻纤维对不同液体的吸附能力不同,其顺序为:生理盐水>A溶液>自来水>蒸馏水;海藻纤维对生理盐水和A溶液的吸附能力随着M/G值的增加而增大,随海藻酸钠用量的增大而减小,当凝固浴用量4%、凝固时间达15 s时,纤维的吸附能力达到饱和.
The M/G values of different sodium alginate were determined by ^1H-NMR. The alga fibers were prepared with wet spinning method. The influence of the M/G values, sodium alginate concentration and coagulating bath concentration and time on the alga fiber adsorption performance was investigated. It was shown from the results that the alga fibers showed different adsorption capacities to different liquids in the order of biological saline 〉 A solution 〉 tap water 〉 distilled water. The adsorption capacity of alga fibers to biological saline and A solution increased with increasing M/G values, decreased with increasing sodium alginate concentration, The fiber adsorption capacity attained the saturation when coagulation bath concentration and 4% and time was 15 s.
