【摘要】 本文应用碘化物——罗丹明——聚乙烯醇体系,根据形成离子缔合物(Pb^?)原理,提出一种灵敏的荧光法测定微量铅。用此法测定工业废水中微量铅(Pb^?)有较好的结果。更多还原

【Abstract】 A highly sensitive fluorimetric method has been develop-ed for the determination of microamounts of lead based on the forma-tion of ion-associate compound of Pb (Ⅱ) with iodide and rhodamineB in the presence of polyvinyl alcohol. The microamounts of lead in industrial wastewater have been deter-mined with satisfactory results.更多还原
