Hydrochemical Characteristics Of Chagan Lake At Low Temperatures

The hydrochemicaln feature of Chagan Lake at low temperature were studied and analyzed. The results from 11 sampling points show that the pH is from 8.39 to 10.09, the hardness is from 40.03mg/L to 71.28mg/L and the mineralization is from 444.93mg/L to 1149.32mg/L. The most Anion is HCO(3)(-), accounting for 60.67% similar to 82.13% of total antions. The most cation is Na(+), accounting for 83.52% similar to 86.69% of total cations. The hydrochemicaln of Chagan Lake is Bicarbonate-Na-I type. Currently N, P content is lower in Chagan Lake, the distribution characteristics in space is analyzed and the preliminary analysis of the distribution of Fe and Mn is taken.
