Description
Cadmium in natural water was determined by means of coprecipitation with zirconium hydroxide and differential pulse anodic stripping voltammetry. Fifty milliliters of a sample solution were added to constant amounts of cadmium standard solutions. After 1 ml of a zirconium oxychloride solution was added, the pH was adjusted to 9.0 with ammonia water (1 : 2). The precipitate was separated by filtration and then dissolved in 25 ml of 4 mol dm-3 hydrochloric acid. This solution was diluted to 50 ml with distilled water. A portion of this solution was employed for determining cadmium. The results were as follows : 1) Zirconium hydroxide was the most effective collector of cadmium when the pH was adjusted to 9.0 with ammonium water (1 : 2). 2) Cadmium took about 90 min to be determined by this analytical procedure. 3) This method is applicable to the determination of trace amounts of cadmium in natural water.
