Abstract
Gelatin forms a weak complex with silver(I) in alkaline media. This complex was studied and was found to be suitable for the spectrophotometric determination of 0.65–2.62 µg ml–1 of hydrazine. The method has been successfully applied to the determination of hydrazine in water using simple, non-toxic and inexpensive chemicals. The molar absorptivity of the complex is 4.2 × 104 l mol–1 cm–1 for the spectrophotometric procedure. The proposed method has a relative standard deviation of 0.51%, a confidence limit (95%) for 13.000 µg of hydrazine (20 determinations) in solution of 12.985 ± 0.031 and a Sandell sensitivity of 7.63 × 10–4µg cm–2. The determination is free from interferences from a large number of foreign substances.
