摘要
地表水中总磷含量高低是评定水质优劣的一项重要指标,分析数据表明丰水期中总磷主要来源于泥沙中吸附的有机磷和无机磷, 而溶解态磷含量较少;水样中总磷含量随着自然沉降时间的延长而逐渐降低。因此样品采集回来后样品的自然沉降时间是影响地表水中总磷测定结果的一个主要原因之一。
The amount of total phosphorus is one of the most important indexs to judge surface water. During the flood, detecting data show that the high amount of total phosphorus mainly come from phosphorus absorbed on mud , but the amount of dissolved phosphorus is low. The amount of total phosphorus in surface water declines gradually with the prolonging of static balance time. Therefore, after being gathered, the static balance time of sample is one of main factors that affect the detecting result.
