在海区监测中,重金属检测很重要。依据国家颁布的检测方法及本单位现有检测设备和条件,对渤海湾海区水质、沉积物进行重金属检测。通过对前处理方法的改进,仪器条件的调整,经过回收率验证,得到比较快捷、准确的方法,供同行参考。一、样品前处理1.水样:从海上各个站位采集来的水 In the monitoring of the sea, heavy metal detection is very important. Based on the testing methods promulgated by the state and the existing testing equipment and conditions of the unit, the heavy metals in the Bohai Bay sea area were measured for heavy metals. Through the improvement of the pretreatment method, the adjustment of the instrument conditions, after the recovery rate verification, a more efficient and accurate method for peer reference. First, the sample pretreatment 1. Water samples: collected from the various stations at sea water
