Abstract
A simple analytical system suitable for nephelometric measurements is introduced
in this article. The electronic and optical components are simplified so that the
apparatus is easily assembled from materials that are generally available. This
instrument is designed for the efficient measurement of anions, and microgram
quantities of ions may be determined by a convenient method of titration. Using this
systarn, the ion detection is performed on several species, and the preliminary results
are reported here. The results from the determination of sulfate and chloride ions show a good detection limit(10 M), and a linearity range of 10 -10 M
