Vanillalrhodanine was found to be an excellent reagent for silver ions. Its 0.2 percent solution in acetone gives a brownish violet precipitate with silver ions in ammoniacal solution. Limit of identification: 0.01γ. Concen- tration limit: 1∶5,000,000. Merecric and merourous ions give same reactions, but they can be removed by the addition of aqueous ammonia and the test is to be carried out in the filtrate. Ferric ions, when present in high concentra- tions, interfere the observation of silver.

3甲氧基4羥基亞苄羅丹寧可以用作銀離子的斑點試劑。其千分之二丙酮溶液與銀離子在含氨溶液中生成棕紫色沈澱。鑑定限度為0.01_γ,濃度界限爲1∶5,000,000。普通離子除汞外皆不干擾。鐵鹽在濃度高時,才妨碍銀的鑑定。

Neosalvarsan is proposed as a reagent for silver ions. It forms a brown insoluble complex. I. L. 2γ; C. L. 25,000. By Job's continuous variation method, light absorption-composition curves were obtain- ed. The maximum corresponds to silver: neosalvarsan = 2: 3. It is proposed that the-As = As-group may be considered as an analytical functional group for silver ions.

(1)新撒爾瓦散可以用作銀離子試劑,與銀離子生成棕色絡合物沉澱。I.L.2γC.L.1∶25,000一般陽離子中只Cu~(++)生成橙黃色沉澱,Fe~(+++)生成紫色沉澱,Hg~(++)生成少量棕綠色沉澱,Hg_2~(++)還原成黑色沉澱。 (2)由Job變更濃度法製得光吸收一組成曲線,最高點相當於銀離子與新撒爾瓦散之此為2∶3。 (3)茲建議偶砷基為銀離子的分析功能團。

Ammonium phenyldithiocarbamate and ammonium phenylhydrazine-dithiocarbamate havebeen found to be suitable reagents for cupric ions.Their 0. 05% aqueous solutions give withcupric ions dark brown precipitate or coloration.Limit of identification of both reagents is 0. 3γ(concentration limit,1:166,000) ,when tests are performed on spot plate.Bismuth,cobaltous,nickelous,mercurous and silver ions interfere.Among them,Co~(++) and Ni~(++) heavily mask thereaction of Cu~(++).But the chelates of Ni~(++) and Co~(++) can...

Ammonium phenyldithiocarbamate and ammonium phenylhydrazine-dithiocarbamate havebeen found to be suitable reagents for cupric ions.Their 0. 05% aqueous solutions give withcupric ions dark brown precipitate or coloration.Limit of identification of both reagents is 0. 3γ(concentration limit,1:166,000) ,when tests are performed on spot plate.Bismuth,cobaltous,nickelous,mercurous and silver ions interfere.Among them,Co~(++) and Ni~(++) heavily mask thereaction of Cu~(++).But the chelates of Ni~(++) and Co~(++) can be separated by extraction with CCl_4 orCHCl_3,in which they are soluble,while the Cu~(++) chelate is insoluble.The color intensity of the chelates obeys the Beer-Lambert's law.The suspension form-ed is stable within 30 minutes and the number of interfering ions is somewhat less.Hence,these two reagents may be used for colorimetric determinations of cupric ions.

1. 苯胺二硫代甲酸铵与苯肼二硫代甲酸铵可用作铜离子的定性试剂,灵敏度皆为0. 3γ(1∶166,000) ,只有 Bi~(+++)、Co~(++)、Ni~(++)、Hg_2~(++)、Ag~+干扰。并可利用生成物在有机溶剂溶解度的不同将铜与钴、镍分离。2. 此二试剂与铜离子的生成物的颜色强度符合 Beer 定律,生成物的悬浮体稳定,可用作铜的比色试剂。
