Possibility of the simultaneous determination of trace metals (Cu, Pb, Cd, Zn) by both anodic stripping voltammetry (ASV) and differential pulse anodic stripping voltammetry (DPS) at a rotatable glassy carbon electrode coated in situ with a thin mercury film was studied. Experimental results showed that the difficulty of simultaneous determination of those metals was connected with the formation of intermetallic compound in amalgam, in particular with the interaction of Zn and Cu.

Possibility of the simultaneous determination of trace metals (Cu, Pb, Cd, Zn) by both anodic stripping voltammetry (ASV) and differential pulse anodic stripping voltammetry (DPS) at a rotatable glassy carbon electrode coated in situ with a thin mercury film was studied. Experimental results showed that the difficulty of simultaneous determination of those metals was connected with the formation of intermetallic compound in amalgam, in particular with the interaction of Zn and Cu. It is not difficult to determine simultaneously Cu, Pb and Cd or Zn, Pb and Cd in non—polluted enviromental samples. For the solution with Cu~(2+), Zn~(2+), Cd~(2+) , Pb~(2+) a new peak before Cu peak is displayed when ASV is used.It is a stripping peak of Zn in Zn_xCu_y. Nonetheless it is possible to determine four metals by ASV simultaneously. When DPS is used the deposition time can be shortened.The methode of the simultaneous determination of Cu, Pb, Cd and Zn was applied to examine the quality of distilled water and tap water.

本文用线性扫描阳极溶出伏安法(ASV)和微分脉冲阳极溶出伏安法(DPS)研究了在同位镀汞玻璃碳电极上同时测定铜、铅、镉、锌的可能性。实验证明同时测定这些离子的困难在于汞齐中形成金属间的化合物;干扰主要取决于铜和辞在汞齐中的相互作用;对一般未污染的环境样品用ASV或DPS同时测定铜、铅、镉或锌、铅、镉不会产生固难;用ASV同时测定铜、铅、镉、锌时在铜的溶出峰前出现一个铜辞化合物中辞的溶出峰,按本文所提出的测量峰电流的方法可以同时测定上述四种离子;用DPS可以用较短的富集时间同时测定这些离子。所制定的方法应用于鉴定蒸馏水及饮用水质量发现,由电加热蒸馏水器得到的蒸馏水会带来铜、铅的污染;济南地区各自来水厂水源中上述离子的含量大大低于国家规定的生活饮用水质标准。

An investigation was made to determine the Cd contents in soils and green -vegetables in Shanghai vegetable-growing region. Average Cd contents in soils and green-vegetables is significantly greater than those in non-polluted area. In general, the contents of Cd in spinach, potato, lettuce, are relatively higher as compared with green -vegetable, but lower in cucumber, cabbage and watershoot. The total Cd in soils increases with the increase of extractable Cd in typical poll- uted soil. A stepwise multiple...

An investigation was made to determine the Cd contents in soils and green -vegetables in Shanghai vegetable-growing region. Average Cd contents in soils and green-vegetables is significantly greater than those in non-polluted area. In general, the contents of Cd in spinach, potato, lettuce, are relatively higher as compared with green -vegetable, but lower in cucumber, cabbage and watershoot. The total Cd in soils increases with the increase of extractable Cd in typical poll- uted soil. A stepwise multiple analysis showed that in field condition, the Cd content in greenvegetable is positively and highly correlated with that in soil regardless of the influence of other elements. The Cd contents in green-vegetables in special soils Cd pollution condition were estimated. Tolerable content of Cd in vegetable and limited soil Cd content for various vegetables are also discussed.

调查了上海菜区土壤和蔬菜中镉的含量。菜区土壤和青菜中镉的平均含量显著高于对照区。菠菜、土豆、莴苣含镉量较高,青菜为中等,黄瓜、卷心菜、茭白较低。土壤受镉污染后总镉升高,伴随可提取态含量也升高。经逐步回归检验,在大田条件下,青菜中含镉量与土壤镉含量有显著正相关,可不考虑其它元素的影响。本文估计了土壤不同镉污染时青菜中含镉量,讨论了蔬菜中镉的容许标准和种植各种蔬菜时的土壤镉限制含量。

This article concerns that the plants have expressed a higher intensity of ,,net photosynthesis and played a more significant role in keeping equilibrium of carbon-oxygen in non-polluted region than in pollutad region.In order to maintain the equlibrium of carbon and oxygen for man to breathe, it was necessary to possess Ficus carica (6.6 trees),Broussonetia papyrifera(4.9 traes) and Liqust-rum lucidum(12.1 trees) in clean area,while 35,6.8 and 51.9 trees respectively in polluted area. The absorption capacity of SO2 of plants in growing period was directly correlative with tha time for contamination. The content of S in foliage in polluted area was obviously higher than that in nonpolluted.The absorption capacity of S mg/day/tree by Ficus carica, Broussonetia Papyrifera and Ligustrum lucidum were 51.23, 171.73 and 15.06 respectively. The efficiencies of net photosynthesis on healthy foliage,foliage with 20% damage spots, with 50% damage spots and 85% damage spots were descent gradually. The leaf area, fresh and dry weight of the plants grown in non-polluted region were higher than that in polluted region.The efficiency of purification of SO2 of the tested trees was calculated.The discussion on the relationship between the purification and absorption ability with green land quota is given at the end of this paper.

本文通过对SO_2污染区与非污染区几种绿化植物的光合作用强度、吸收SO_2能力以及一些生物学性状的测定,计算了维持一个人呼吸达到碳氧平衡所需被测植物的株数和占地面积;净化已知SO_2总量应有的绿地面积,并探讨了植物的净化能力与绿地定额的关系。
