标题：Quantitative Determination of Cadmium, Copper, Manganese, and Lead in Water by Combination of Coprecipitation with Zirconium Hydroxide and Flame Atomic Absorption Spectrometry
摘要：A method for quantitative determination of four harmful metals, Cd, Cu, Mn, and Pb in water by means of coprecipitation with zirconium hydroxide, Zr (OH)4, followed by flame atomic absorption spectrometry has been developed. Because no extraction process of the metal chelates with organic solvents is required, and because Zr shows low toxicity to mammals, this procedure is free from hazard to the health of laboratory workers engaging in metal analysis. The results of recovery tests indicated that the recoveries of the metals by the above procedure are satisfactory (more than 98%).
