摘要
在微酸性介质下,硅酸与≥70℃的钼酸铵在2min之内生成硅钼杂多酸,水浴冷却,在草酸存在下,用较低量的硫酸亚铁铵还原生成硅钼蓝,测其吸光度。
Under micro - acidic medium condition, silicon acid reacts with ammonium molybdate of more than 701 and Si - Mo heteropolyacids was produced with two minutes. By means of water cooling, Si - Mo blue was formed by reduction react of little ferrous sulfate ammonium with oxalic acid,then luminosity absorption was measured.
