• By the use of a new reagent, 1,1-bis(<I>p</I>-dimethylaminophenyl)-3-phenyl-2-propynylium chloride, <I>i.e.</I>, one of the ethynologs of Malachite Green, micro amounts of perchlorate ions could be extracted into chlorobenzene and determined spectrophotometrically. Beer's law holds over the range of 4×10<SUP>−6</SUP>–2.5×10<SUP>−5</SUP> M (M=1 mol dm<SUP>−3</SUP>); ε=4.0×10<SUP>4</SUP> dm<SUP>3</SUP> mol<SUP>−1</SUP> cm<SUP>−1</SUP> at 690 nm.
