The paper studies on the main physics- chemical properties of watersolubleions in atmospheric particulates and their relations with precipitation in different seasons of Lanzhou.
These compounds are soluble in water, and contains the hemiacetal hydroxyl free, so in alkaline solution can reduce silver ions and copper ions.
这些化合物能溶于水，并含有游离的半缩醛羟基，所以在碱溶液中能还原银离子和铜离子。

The mass concentration, water-solubleions and elemental composition of fine particles were detected by the weighing method, ion chromatography, inductively coupled plasma chromatography separately.
