Spectrophotometric Determination of Antimony in Industrial Waste Waters with Iodide and Amidines
Abstract
A new method has been developed for determination of trace amounts of antimony in industrial waste waters. It is based on the reaction of antimony(III) with iodide over 1.0–4.0M H2SO4, and extraction of the iodo complex with amidine(HA) into chloroform as a [Sb2I6HA] complex. The molar absorptivity of the complexes with 9 various amidines are found to be in the range of (4.1–6.8) × 103 1 mol−1 cm−1 at λmax. Of these, the simplest compound, N, …
