Download or read book Comparison of Methods for the Determination of Total Available Residual Chlorine in Various Sample Matrices written by Daniel F. Bender and published by . This book was released on 1978 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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. This report covers a period from March 1976 to November 1976 and was completed as of November 12, 1976.

This book was released on 1953 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Continuous recording of residual chlorine is not a new idea. Rather this has been the aim of scientists and operating personnel since chlorination of potable water was first placed on a continuous basis in 1908. Actually the development of reliable equipment for this purpose could not take place until the nature and characteristics of residual chlorine in water, in small concentrations (0.1 to 10.0 ppm), had been thoroughly studied and certain instruments such as the photoelectric cell and amperometric titrator had been perfected. The perfection and acceptance of the photoelectric cell offered one of the first avenues of approach to the problem. Early work was devoted largely to the measurement and recording of the various intensities of color, which are proportional to the amount of chlorine present, produced by the addition of certain reacting chemicals, such as potassium iodide or orthotolidine. Several instruments utilizing this principle were constructed and placed in operation during the early thirties. Some were notably successful, particularly those making use of orthotolidine. However, practically every scheme using the photoelectric cell method was subject to certain fundamental errors, the most common of which was the accumulation of material on the glass surfaces of the water cell. These accumulations changed the intensity of the color measured by the photoelectric cell and introduced errors that were difficult to overcome. In addition, the equipment was either complicated or required a degree of skill in operation.
