Abstract A spectrophotometric investigation of oxidation of chondroitin-4-sulfate
(CS) as a sustainable and biodegradable sulfated macromolecule by oxyanion permanganate ion as multi-equivalent oxidant in acid perchlorate solutions at a constant
ionic strength of 2.0 mol dm-3 has been studied. The experimental results on the
influence of the concentration of the reactants the reaction rates revealed first-order
dependence in MnO4–
, fractional second-order in [CS] and fractional first-order with
respect to the hydrogen ion concentration. The hydrogen acid concentration dependence of the rate constants indicated that the oxidation rates were increased with
increasing the acid concentration which means… More >
