Micro-level Estimation of Mercaptoacetic Acid Using its Inhibitory Effect to Mercury Catalyzed Ligand Exchange Reaction of Hexacyanoruthenate(II)
The sulfur-containing bioactive molecules (soft base) tends to bind strongly with Hg(II) (soft acid). thereby inhibiting the mercury (II) catalyzed exchange rate of cyanide ligand from [Ru(CN)(6)](4-) by pyrazine. This inhibitory effect of Mercaptoacetic acid (MAA) encourages us to establish a new kinetic method for its micro-level estimation. Optimized reaction condition viz. 6.25×10(-5) M [Ru(CN)(6)(4-)],[pH = 4.0, 7.5×10(-4) M [Pyrazine], 0.05 M KCl, 8.5 x 10(-5) M [Hg+2] and 45 (+/- 0.1) degrees C temperature were utilized for the kinetic spectrophotometric investigation at 370nm (lambda max of Ru(CN)(5)Pz](3-) complex). The modified mechanistic scheme for inhibition caused by sulfur donor ligand, MAA has been Proposed. The proposed analytical method provides the detection of MAA up to 2.0 x 10(-6) M. indicates that the methodology can be effectively and economically employed to analyze the biological samples having MAA. This method can also be convincingly adopted for the quality check of MAA containing industrial products.
