滴定沉淀法测定尼龙镀银纤维银含量

Silver Content Determination of Nylon Silver-plated Fiber by the Precipitation Method

文章利用化学滴定沉淀的方法对尼龙基镀银纤维中的银含量进行分析测定,采用磺酸化法对样品进行溶解,加盐酸生成沉淀,用离心后烘干的方法提取出沉淀,初步探讨滴定沉淀法测定尼龙镀银纤维银含量的可行性。

The chemical precipitation titration method for silver content determination of silverplated fiber was used.The samples were dissolved by the sulfonic acid method,and the HCl was added to produce precipitation,and then the precipitation was collected by centrifugation and drying.The feasibility of silver content determination of nylon silver-plated fiber by the precipitation method was discussed.
