摘要
浮尘天气是由于空气中的硅酸盐土壤胶团物质增多导致。长时间的采样可使聚丙烯滤膜上富集大量的硅酸盐,测定硅酸盐含量时,硅酸盐含量的增高会对硅钼蓝显色反应产生抑制作用,使得测定结果偏低,导致测定的准确度降低。
The dust weather is due to the increase in the amount of silicate soil micelles in the air. Long sampling can enrich the polypropylene fltration membrane with a large amount of silicate, when determining the silicate content, the increase of silicate content can inhibit the reaction of the molybdenum blue color reaction, which makes the measurement result low and the accuracy of the measurement decreased.
