摘 要:
对太湖典型湖区水体中的胶体态痕量金属进行了定量分析.结果表明,太湖春季水体中胶体态Cu,Zn,PB,Fe,Mn和Cd的浓度分别为0.46-0.86μg·l^-1,2.06—8.24μg·l^-1,2.620.70μg·l^-1,3.48.24.79μg·l^-1,0.31—1.62μg·l^-1和6.71—17.94ng·l^-1,平均分别占各自总溶解态(〈1μm)的22.3%.26.3%,20.7%,58.9%,40.4%和59.2%,而胶体态Cu,Pb,Fe,Mn和Cd平均分别占各自总量的17.4%,19.1%,55.1%,1.98%和52.8%.[著者文摘]

Abstract:
Colloidal trace metals in the waters of lake Taihu were analyzed quantitatively. Results showed that contents of colloidal trace metals in lake Taihu were 0. 46-0. 86μg ·l^-1 (22. 3% ) of the totally dissolved partition) for Cu, 2. 06-8. 24 μg ·l^-1 (26.3%) for Zn, 2. 62-3. 70μg ·l^-1 (20.7%) for Pb, 3.48- 24.79μg·l^-1 (58.9%) for Fe, 0.31-1.62μg ·l^-1 (40.4%) for Mn and 6. 71-17.94ng ·l^-1 (59.2%) for Cd. And averagely, the colloidal Cu, Pb, Fe, Mn, and Cd occupied 17.4%, 19. 1%, 55.1%, 1.98% and 52. 8% of their total contents in lake water respectively.[著者文摘]
