Basic research on adsorption and desorption of metal ions for silk

考察了天然染料对真丝染色时作为媒染剂的铜、铁、铝的吸附和解吸性能。并考察了吸附金属对真丝染色性能的影响。实验结果证实，随着处理时间的延长，丝纤维对铜、铁、铝的吸附量增加。铜和铁在前5分钟的吸附量与最大吸附量相近。早期蚕丝纤维中铜、铝的解吸比铁的解吸容易。但在不受干扰的静置过夜后，蚕丝纤维解吸铁后的电导率提高了约10倍。并观察到铜吸附在蚕丝纤维上抑制了酸性橙7在蚕丝纤维上的吸附。在此之后，我想测量丝纤维上吸附金属的最大量。并且，我希望澄清金属对丝纤维的吸附特性。

Adsorption and desorption of copper, iron and aluminum that used as mordant when silk was dyed by natural dye were examined. And, influence of the adsorbed metal on the dyeing properties of silk was examined.The results of examinations, this confirms that adsorption of copper, iron and aluminum on silk fiber increased in process of treating time. And, copper and iron were adsorbed similar to maximum adsorption in first 5 minutes.The desorption of copper and aluminum from silk fiber were more easy than that of iron in its early time. But the electric conductivity under desorption of iron from silk fiber increased by about ten times that of first time after standing undisturbed overnight.And it was observed that copper adsorbed in silk fiber inhibited the adsorption of C.I.Acid Orange 7 on silk fiber.After this, I would like to measure the maximum quantity of adsorbed metal to silk fiber. And, I hope to clear adsorbing characteristics of metal to silk fiber.
