| 摘 要： | 试样经草酸、双氧水分解后，以盐酸羟胺破坏掉多余双氧水。以标准样品作参比，在硫酸－柠檬酸介质中，用钼酸铵显色，抗坏血酸还原，生成稳定的硅钼蓝。此方法可测定１．０％以下的硅，具有快速、准确、灵敏度高等优点。

| Abstract: | The unnecessary hydrogen peroxide solution is cleared away with hydrochloric acid after the sample has been decomposed by oxalic acid and hydrogen peroxide solution ,The stable silcon molybdenum blue has been producted in the medium of sulphuric acidcitric acid.It is showed colour by ammonium molybdate and restored by ascorbic acid.This method may determinate the silicon contained <0.1%,and has some advantages such as high speed,degree of accuracy and sensitivity. |
