几种溶样方法在锌精粉测定中的探索

The Exploration of Some Dissolving Sample Means in the Determination of Zinc Refined Powder

主要提出了几种锌精粉的溶样方法,通过添加盐酸、硝酸、氢氟酸、高氯酸,加热溶解,主要是氢氟酸能打开矿物中的硅酸盐,使溶样更加完全。结果比较了国标和常用方法,对初学者和初级实验室容易掌握,有较强的推广性。

Some dissolving sample means was put forwards in the determination of Zinc refined powder. The samples were dissolved by heating via appending hydrochloric acid,nitric acid,hydrofluoric acid and Perchloric acid. The sample was dissolved in its entirety because hydrofluoric acid dissolved silicate. Compared with state the standard and customary means , the result was satisfactory. These means wrer easy to the primary learners.
