A new method for the successive determinations of Cu~(2+),Zn~(2+) and Pb~(2+) is given by com- prehensively using DDTC and Oxine.The method have many advantages,such as saving analyte,simplifying analytical process and so on.It can be used for the actual analysis of the most tin-bronze and for the determination of some enviromental samples.

本文提出了一个综合使用 DDTC 和 Oxine 联合测定铜、锌、铅的新分析方法。从而简化了分析手续,节省了试剂,可用于大多数锡青铜合金的实际分析及一些环境样品中相应组分的测定。

The method of the rectification in the normal pressure is used to refine the crude Zinc which is smelted by the pyrometallurgical method. The possibility of the evaporation of crude Zinc is discussed in this paper.

目前国内外皆采用常压精馏的方法精炼火法生产出的粗锌。本文探讨了采用真空蒸馏法精炼粗锌的可能性。由理论计算得到650℃时,在Zn—Ph及Zn—Cd系富锌端,分离系数βPb=2.274x10~-3,βCd=26.752,说明锌铅分离效果很好,锌镉仍有可能分离。小型试验研究了温度、残压、熔体深度、蒸馏时间等因素对锌、铅、镉蒸馏的影响,得出了真空蒸馏粗锌的有关基本规律和作业条件。

1 mL well-mixed oil-sample is heated gently on a temperature-controlled electric heater, and ashed in a muffle furnace. The sample is then changed into metal oxides. The contents of the seven metals are simultaneously determined by Atomic Emisson Spectrograph (AES) with alternating current are and small-hole powder way. The measure precision is less than 10%, the results of several oil samples are well agreed with the results of FAS-2C in USA.

取1mL搅匀的油样,经电炉干馏,马弗炉灼烧后,得到各金属元素的相应氧化物,采用发射光谱交流电弧光源、小孔粉末制样技术,直接测定主要磨损金属元素铜、铁、锌、铅、铝、铬和硼的含量。测定精度好于10%,分析结果与美国贝尔德公司的FAS-2C型光电直读光谱仪所得数据基本一致。
