摘要:
在pH=5.6HAc-NaAc缓冲溶液介质中和Tween-80和β-环糊精存在下,锌(Ⅱ)与5-Br-PADAP形成紫红色包含络合物,提高了反应体系的灵敏度和选择性,且准确、简便、快速.用于天然水中微量锌(Ⅱ)的测定,结果良好.
Abstract:
For determining trace zinc in natural water, the author presents a handy and quick method with precision results. In the presence of Tween-80 and β-cyclodextrin, zinc(Ⅱ) reacts with 5-Br-PADAP to form a purple inclusion complex in the medium of acetic aci
