A modified method is described for the use of 0.5M sulfuric acid-0.5M tartaric acid as a supporting electrolyte in the polarographic determination of titanium. The interferences due to iron (Ⅲ) and copper are reduced with iron powder.In comparing with Graham's method, the amount of tartaric acid reduces to half, and the removal of interferences by iron powder proves more simple and effective than Graham's and Zan'ko's methods.The method is applied to copper, lead, zinc and titaniferous iron ores with satisfactory...

本文介紹在0.5M硫酸-10%酒石酸(約0.5M)底液中,用鐵粉還原銅,鐵等干擾元素,作钛的極譜法測定。應用於銅礦、鉛鋅礦及钛磁鐵礦中,操作簡便迅速,並与比色法結果相符。在酒石酸用量上較Graham法减低一半,干擾物採用鐵粉還原也較Graham法及法迅速和有效。惟钼的干擾不能消除。

1. For the polarographic determination of vanadium in petroleum ash, large quantities of Fe and Ni and small quantities of Co, Zn, Pb and Cu were separated by the electrolysis with mercury cathod. A small quantity of ferric salt and NaOH were then added to separate Ti through coprecipitation with Fe(OH)_3. Under this condition, the coprecipitation loss of vanadium was found to be negligible. 2. The polarographic medium for determination of vanadium consisted of 1.8 N NH_4OH, l N NH_4Cl, 0.01% gelatin and 1%...

Since the discovery of antitumor activity of Sb-57 and Sb-71, about 50 analogs of them have then been tested in mice bearing Ehrlich ascites carcinoma or sarcoma 180. The main results were as follows: 1. The antimonial chelates of five complexones exhibited marked inhibiting action on Ehrlich ascites carcinoma in mice. They were the salts of EDTA-Sb (table 6-Ⅰ) and PDTA-Sb (Ⅳ), N-substituted analogs of EDTA-Sb (Ⅱ), ATA-Sb (Va) and antimonial derivatives of its analogs (Ⅶ), and CDTA-Sb (Ⅸf). Among these compounds...

Since the discovery of antitumor activity of Sb-57 and Sb-71, about 50 analogs of them have then been tested in mice bearing Ehrlich ascites carcinoma or sarcoma 180. The main results were as follows: 1. The antimonial chelates of five complexones exhibited marked inhibiting action on Ehrlich ascites carcinoma in mice. They were the salts of EDTA-Sb (table 6-Ⅰ) and PDTA-Sb (Ⅳ), N-substituted analogs of EDTA-Sb (Ⅱ), ATA-Sb (Va) and antimonial derivatives of its analogs (Ⅶ), and CDTA-Sb (Ⅸf). Among these compounds the propylamine salt and morpholine salt were more potent than the others (such as sodium salt). 2. Ten kinds of metal complex (Hg, Bi, Pb, Zn, Mn, Cu, Co, Ni, Sn and Ba) of ATA and EDTA (Ⅲ, Ⅴ and Ⅷ) were prepared and examined for their activities, but none of them showed any inhibitory action on experimental tumors. The chelating agents (EDTA, PDTA and ATA etc.) alone also had no therapeutic effect on Ehrlich ascites carcinoma or sarcoma 180 in mice. 3. EDTA-SbNa, PDTA-SbNa (Sb-57) and ATA-Sb (Sb-71) produced a slight inhibition on the growth of sarcoma 180. The chemical feature and pharmacologic effect of antimonial chelates of EDTA and ATA are also discussed in this paper.

銻胺羧螯合物是本所发現的新型抗肿瘤药物,本文继續探討此类化合物的化学結构与疗效之間关系。发現:(1)銻与5种不同类型的胺羧螯合剂結合的制剂,例如EDTA-Sb(Ⅰ)和PDTA-Sb(Ⅳ)的不同盐类,N取代的EDTA-Sb(Ⅱ),ATA-Sb(Ⅴa)及其类似物(Ⅶ)和GDTA-Sb(Ⅸf)对小鼠Ehrlich腹水瘤均有明显的抑制作用,其中乙二胺四乙酸銻丙基銨盐和对氧氮六环盐的疗效較其鈉盐为佳。(2)汞、鉍、鉛、鋅、錳、銅、鈷、鎳、錫和鋇10种金属胺羧絡合物(Ⅲ,Ⅴ及Ⅷ)及EDTA,PDTA和ATA对Ehrlich腹水瘤和肉瘤180均无疗效。(3)EDTA-Sb-Na,PDTA-Sb-Na和ATA-Sb对肉瘤180稍有抑制作用。(4)銻胺羧螯合物抗癌作用的基本結构可能为一个含銻的螯合物分子中拥有以氮为中心而具有三个以上的羧甲基。
