摘要:
在乳化剂 OP 存在下,用5-Bi-PADAP 显色反应分光光度法连续测定水中微量锌、铅和镉。采用巯基棉富集分离,以差减法消除干扰,提高了体系的灵敏度和选择性,且快速、简便、准确。可用于测定天然水中微量锌、铅和镉。
Abstract:
In the presence of the emulsifier OP.a spectrophotometry of trace zinc,lead and cadmium in water was carried out continously by means of the color-reaction of 5-Br-PADAP.For improving the sensitivity and selectivity of the system, sulfhydryl cotton enrich
