| Abstract | Ten different methods for determining total available residual chlorine, all based on the iodine-iodide reaction, were tested without modification on four sample matrices. Their precision was determined by seven replicate determinations. Accuracy as compared to the iodometric starch titration method, was determined in terms of percent yield. Observations regarding advantages, disadvantages, deviations from the expected and problems, involved in the determination are recorded. The data are presented in tables arranged for instructive purposes and in a figure intended to present the data in reduced form for easier appraisal. The information obtained can be used by the analyst in determining which method is most suitable for a particular matrix. The data show the importance of the nature of the sample matrix. The necessity of comparing several methods in order to be certain of the accuracy is also obvious given the data. |
