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%...

1.在进行石油灰中钒的极谱测定以前,应先用汞阴极电解法分离少量的钴、铅、锌、铜和大量的铁和镍,再将少量的Fe~(+++)离子加入电解后的溶液,利用以NaOH沉淀Fe(OH)_3时钛的共沉淀作用,将钛分离。 2.在分析石油灰时,钒的极谱基底液成份应是1.8N NH_4OH、N NH_4Cl、0.01%白明胶及1%Na_2SO_3。 3.我国某炼油厂的石油灰中含钒量0.735% 4.鉴于此项石油灰中含有多量的镍和钒,建议有关部门考虑其提炼价值。

Rapid polaropraphy with the mercury film electrode was applied to the simultaneous determination of Cu2+, Pb2+, Cd2+ and Zn2+ in water. When these ions were electrolyzed in 0.15M NH4Gl medium for 10 min. at -1.3V (VS. Ag- Hg electrode), the metals were elcctrodeposited on a mercury film electrode, and an anodic dissolution curve was recorded by an X-Y functional recorder from -1.3V to -0.1V. The peak heights were linear with concentrations within the range or 10-6M-10-8M for Cu, Pb, Zn and of 10-6M-10-9M for...
