In pH 5.3-6.8 Britton-Robinson buffer medium, Cefotaxime sodium can react with HgCl2 to form 1:1 anionic chelate, which can further react with basic triphenylmethane dye such as crystal violet, methyl violet, ethyl violet, brilliant green, iodine green, methyl green and malachite green to form ternary ion-association complexes. As a result, the resonance Rayleigh scattering spectrum was enhanced greatly.
