| Abstract: | A method for the estimation of cadmium in catalytic concentrations (2x 10-7 to 2x 10-5 M) had been developed by measuring its catalytic effect on the auto oxidation rate of ammonium sulphite. Measurements have been done on the homogenous reaction rates by the thermal-flow method. The rate of reaction is followed by monitoring the temperature change along the flow path by sensitive thermocouples and the degree of conversion is calculated from the temperature change and the known heat of reaction. On the basis of the experimental results for the catalysed reaction, the following rate expression is derived: -d[O2]/ dt = k’[O2]0 [SO2]3/2[ cd+2]1/2 Where k’ is rate constants of intermediate steps involving free radicals. This simple dependence f rate on the Cadmium concentration leads of developing a kinetic method for estimating Cadmium concentration from its catalytic effect on this particular reaction. For a fixed initial [SO32-]= 0.06 M and [O2]= 0.002M the plot of rate of oxidation versus Cadmium concentration is linear with a slop of 0.05 for Cadmium concentration varying from 2x 10-7 M to 2x10-5M. The method is sensitive up to 10-7M concentration and the maximum error is approximate 3.4%. |
