摘要
文章采用熔融法分解试样,热水浸取,在一定的酸度下,硅与钼酸铵生成硅钼杂多酸,以抗坏血酸使之还原成硅钼蓝,用差示分光光度法测定,结果令人满意。
The sample is decomposed through melting. By thermal flooding, under a certain acidity, silicon and ammonium can generate Si-Mo heteropoly acid so as to anti-ascorbic-acid to be reduced to silicon-molybdenum blue. Using differential Spectrophotometric Determination, the resuhes are satisfactory.
