摘要
飘尘中的二氧化硅用盐酸溶解后,在氢氧化钠的碱性条件下与钼酸盐生成黄色的硅钼酸进行比色测定。
The silica-containing atmospheric suspended particles samples were solved with hydrochloric acid. The liquid reacted with sodium hydrate produced soluble sodium silicate (Na2SiO2). Then microsilicium reacted with molybdate produced yellow silicomolybdic acid in the liquid. Final carried on determination of spectrophotometry.
