✦ Synopsis

ManganeseNII) (O-100 pg) can be determmed spectrophotometncally at 548 nm after Its extraction as benzyltr~butylammomum permanganate, at pH 6, mto chloroform The effects of pH, reagent concentrations and &verse ions are reported The system has been apphed to the detemunation of manganese m a vanety of steels For the determmation of 60 pg of manganese the relative standard deviation was 0 19% (7 measurements)
