摘要:

为深入了解海藻酸纤维吸附及释放锌离子的性能,通过湿法纺丝方法制备纯海藻酸锌纤维,并通过盐酸处理海藻酸钙纤维制备海藻酸纤维。在不同时间、温度及锌离子浓度的条件下研究海藻酸纤维吸附锌离子的性能。结果显示,通过控制硫酸锌及海藻酸纤维的质量比可制备锌离子含量不同的海藻酸纤维。采用生理盐水及不同浓度的蛋白质水溶液处理海藻酸锌纤维,并测试接触液中锌离子的浓度发现,低温时比高温下的锌离子释放量大,溶液中的蛋白质可促进锌离子的释放。

Abstract:

With a view to better understanding the absorption and release of zinc ions by alginate fibers, this paper prepared pure zinc alginate fibers by a wet spinning process and prepared alginic acid fibers by treating calcium alginate fibers with hydrochloric acid. The absorption of zinc ions by alginic acid fibers was studied under different times, temperatures and zinc ion concentrations. Results showed that by controlling the weight ratio between alginate fiber and zinc sulphate, it is possible to prepare alginate fibers containing different amount of zinc ions. This paper used saline and aqueous solutions with different protein contents to treat zinc alginate fibers and test the zinc ion concentration in the contact solution. Results showed that the amount of zinc ion released is higher at low temperature than at high temperature, with the protein in the solution accelerating the release of zinc ions.
