| Abstract: | kinetic
spectrophotometric assay based on the iodinecatalyzed Ce4+As3+ redox reaction is presented for
the determination of iodine. No water bath is needed. The determining time was shortened. The
purification of reagent, the vessel of reaction, and the selection of terminating reagent were
discussed. The correlation coefficient of the standard curve is higher than 0.999. |
