| 摘 要： | 采用电感耦合等离子体光谱法（ICP-OES）,在一定条件下、不同的储存容器中,同时测定铅、镉、铬、镍、钴、锑、锌、砷8种有害物质的检测量与初始量的变化率。试验结果表明,不同材质的容器中,相同种类重金属的检测值和初始值的变化率不同;相同材质的容器中,不同种类重金属的检测值与初始值的变化率也不相同。综合分析,较适宜储存重金属溶液的容器材质为氟化乙烯丙烯共聚物。

| Abstract: | The influence of storage containers on hazardous substances of sample was evaluated. Hazardous substances of heavy metal (lead, cadmium, chromium, nickel, cobalt, antimony, zinc and arsenic) were found in synthetic samples detected by inductively coupled plasma optical emission spectroscopy (ICP-OES) in different storage containers. The effect of materials of containers was evaluated by the change of detection value and initial value of hazardous substances. Results showed that the variation of the same type of hazardous substances was different when stored in different containers. Different kinds of materials of container were suitable for different kinds of hazardous substances. The most suitable material was Fluorinated ethylene propylene produced by foreign. |
