説明

ο-Aminobenzaldehyde-ethylenediimine was used as a reagent for colorimetric determination of copper and nickel in iron and steel. The result indicated that copper can be estimated by extracting it with 0.01% reagent in benzene from ammonia alkaline solution not containing large amount of ammonium salt or from sodium hydroxide alkaline solution containing tartaric acid. The presence of nickel can be corrected. Nickel in sodium hydroxide alkaline solution containing tartaric acid can be precipitated by use of 0.1% alcoholic solution of the reagent and estimated by extracting with benzene. The presence of copper can be corrected. Also, the estimation of copper in the presence of iron has been tried. Copper is precipitated in sodium hydroxide alkaline solution containing tartaric acid, filtered, and weighed as oxide after ignition.
