摘要
用乙酰丙酮 (HAA)掩蔽和解蔽 Mg2 +,在同一溶液、同一 p H值、指示剂和标准溶液(EDTA)直接滴定 Ca2 +、 Mg2 +。已用于测定工业废水。
While the Mg 2+ was masked and demasked with HAA,the Ca 2+ ?Mg 2+ can be determined directly by the chelatometry in same factors that as the solution,the pH,the indicator and the standard solution.The method were used for determination of Ca 2+ ,Mg 2+ of some industrial waste water and a Molybdenum concentrate. The results is satisfactory.
