摘　　要：Introduction Since it was found that cetyltrimethylammonium bromide (CTMAB) can increase greatly the sensitivity of the tin (Ⅳ)-pyrocatechol violet (PV) system, the micellar speetrophotometric determination of tin (IV) has been developed extensⅣely. The most widely used acidity dyes are PV and Bromopyrogallol Red (BPR). They have
