为了研究绒布河源区夏季河水的基本化学特征 ,野外采集水样 1 1 7份 ,采用 PE- 2 380型原子吸收光谱仪测定样品的阳离子 ,Dionex- 1 0 0型离子色谱仪测定阴离子 .结果表明 :1绒布河源区河水为 HCO3,SO4- Ca型 .其离子浓度顺序为 :Ca2 +>K+>Na+>Mg2 +,SO2 -4 >Cl- >NO- 3 .2河水中离子 Ca2 +、Mg2 +、SO2 -4 之间 ,以及 K+和 Na+之间有很好的正相关关系 ,河水化学组成大部分来源于当地岩石的风化分解 .3整个夏季河水各月离子平均浓度和流量有良好的正相关关系 ,流量大的月份 ,各离子平均浓度也大 ,反之亦然 .
In order to study the basic chemical characteristics of the summer river water in the flannel area, 117 samples of water were collected from the field, and the cation of the sample was determined by PE-2 380 atomic absorption spectrophotometer. The anion was detected by Dionex-1000 ion chromatography. 1 The velvet cloth in the Heyuan area was HCO3 and SO4-Ca, with the order of Ca2 +> K +> Na +> Mg2 +, SO2-4> Cl-> NO- 3 .2 The ions of Ca2 +, Mg2 + SO2-4, and between K + and Na +, with most of the chemical composition of the river coming from the weathering decomposition of the local rocks.3 There was a good positive correlation between monthly mean ion concentrations and fluxes over the summer , The monthly flow of large, the average concentration of ions is also large, and vice versa.
