摘要：

Manganese(VII) can be determined spectrophotometricaly at 546 nm after extraction as dimethyldistearylammonium permanganate into dichloromethane. The effect of pH, reagent concentration, conditions and diverse ions are reported. The calibration graph is linear up to 110 mu g Mn. The apparent molar absorptivity is 2.3 x 10(3) l mol(-1) cm(-1). The relative standard deviation is 0.3% (n = 10) for 100 mu g of Mn. The system has been applied to a range of steels. (C) 1999 Elsevier Science B.V. All rights reserved.
