Inductively Coupled Plasma Atomic Emission Spectrometric Determination of Copper by Suction-Flow On-Line Liquid–Liquid Extraction of Its Macrocyclic Dioxotetramine Chelate
摘要:
所描述的流体歧管可通过抽吸流进行液-液萃取,将离散水样中的铜(II)作为其大环二氧四胺(6-十六烷基-1,4,8,11-四氮杂环十四烷-5,7-二酮,HDC)螯合物萃取到氯仿中。有机提取物通过蠕动泵依次进入电感耦合等离子体。对于 100 ng cm-3 的铜(II),检测限为 1.5 ng cm-3,相对标准偏差为 2.2%(n=10)。

The macrocyclicdioxotetra-amine (2) acts as a carrier for the membrane transport of copper(II) ions against the concentration gradient by the coupled counter-transport of protons and is potentially useful for solventextraction of copper.
