Abstract
A new spectrophotometric method has been applied to the determination of zinc in bottled mineral water (with and without gas), refreshments, vinegar, and table salt. The method introduces the 1-[di-(2-pyridyl)-methylidene]-5-(salicylidene)-thiocarbo hydrazone (DPST) as chromogenic reagent. This procedure is simple, rapid, reproducible and does not demand costly outfit and chemicals.
摘要
一种新的分光光度法已应用于瓶装矿泉水（有气和无气）、茶点、醋和食盐中锌的测定。该方法采用1-[二（2-吡啶基）-亚甲基]-5-（水杨醛亚基）-硫代碳酰肼（DPST）作为显色剂。该方法简单、快速、可重复，且不需要昂贵的仪器和化学试剂。
