• General Description: Ethanedioic acid diammonium salt (ammonium oxalate) is an effective precipitating agent for cadmium in gravimetric analysis, forming an insoluble cadmium oxalate trihydrate (CdC2O4·3H2O) in neutral, diluted solutions. It is preferred over oxalic acid due to the lower solubility of cadmium oxalate in its excess, ensuring accurate and precise results. The method involves precipitation, washing with alcohol-water mixtures, drying under reduced pressure, and weighing, with minimal interference unless alkali or ammonium salts are present. This approach is also adaptable for determining zinc and bismuth as oxalates.

Eine gewichtsanalytische Schnellmethode zur Bestimmung des Cadmiums als Oxalat

10.1007/BF01364636

The study presents a gravimetric method for the determination of cadmium as oxalate. The method involves precipitating cadmium from a neutral, diluted solution using a slight excess of an ammonium oxalate solution. The precipitate forms as CdC2O4·3H2O, which is insoluble in the precipitation solution and the washing liquid. After the precipitation, the solution is decanted, and the precipitate is washed with a mixture of alcohol and water, followed by thorough washing with alcohol and ether. The precipitate is then dried under reduced pressure and weighed. The cadmium content is calculated from the weight of the precipitate using a specific factor. The study highlights the effectiveness of ammonium oxalate as a precipitating agent, noting that it is preferable to oxalic acid because the cadmium oxalate is less soluble in an excess of ammonium oxalate compared to oxalic acid. The method is precise and accurate, with results comparable to other established cadmium determination methods. However, the presence of alkali or ammonium salts can interfere with the method, necessitating their removal before analysis. The study also mentions that similar methods can be applied to determine zinc and bismuth gravimetrically as oxalates, with related experiments underway.
