[Extraction-spectrophotometric determination of copper in tablets and injections of Chinese medicine].
摘要
Cu reacts with neo-cuproin and eosin Y to form a coloured associated complex. In chloroform its apparent E value is 6.83 X 10(4) 1 mol-1 cm-1 at lambda = 544 nm. We used this system to determine the contents of trace copper in some tablets and injections of Chinese medicine. This method is simple, highly sensitive and selective.
