摘要：

The research shows that the chromogenic reaction of copper(Ⅱ) with N-Butyl-N'-(Sodium p-Aminobenzene Sulfonate) Thiourea(BPT) is highly sensitive in an acid medium. The operation is simple and easy:it needs no extracting, and the selectivity is better. The proposed method was used to determine copper in lead minerals with satisfactory results.
