Abstract
A highly sensitive and selective procedure for spectrophotometric determination of silver has been developed. At pH 9.2, in the presence of Triton X-100, silver forms a dark red-violet complex with cadion 2B which has an absorption maximum at 565 nm. The molar absorptivity is 1.0 × 10 5 l.mole −1·cm −1. Beer's law is obeyed for silver in the range 0.02–0.8 μg ml . The colour reaction, if EDTA is used as a masking agent, is free from interference by the 20 cations and 19 anions investigated. Only Cl −, Br −, I −, S 2− and CN − interfere and must be absent. This method has been used to determine silver in waste-water.
