Database of the amount of ammonia nitrogen, dissolved organic carbon, cations and anions of river water from Hulugou outlet (June to August, 2012)

1. Data overview:

this data is sampled from June 21, 2012 to August 25, 2012. The sampling frequency is once a week.

The sampling point is located at the outlet flow weir of hulugou small watershed in the upper reaches of Heihe River, with the longitude and latitude of 99 ° 52 ′ 47.7 ″ E and 38 ° 16 ′ 11 ″ n.

2. Data content:

this data set includes the ammonia nitrogen value, Doc value and anion ion value of river water at the outlet of the basin.

Data acquisition means: ammonia nitrogen value is measured by hash DR2800 ultraviolet spectrophotometer; doc value is measured by analytikjena multi n / c3100 total nitrogen and total carbon tester; anion value is measured by 761 / 813 ion chromatograph of Swiss Wantong; cation is measured by iris intrepid Ⅱ xspicp-aes of us thermoelectricity.
