โœฆ Synopsis

The fluorescence lifetime and quantum yield of malachite green leucocyanide has been measured in cyclohesane, ethanol and acetonitrile and has been compared with the corresponding values fcr N,Ndimethylaniline in the same solvents_ In cycIohexane, the data is essentially identical, but in polar solvents there are large differences. These are attributed to the fact that the leucocyanide photoionized to malachite green cation from its first excited singlet state:

The oxidation kinetics of malachite green (MG) with peroxydisulphate ion (PDS) were investigated by monitoring the absorbance change at 618 nm, in aqueous solutions under buffered and unbuffered conditions. Under both conditions, the reaction had first order dependence on reductant and a fractionah&
