摘要
水文地质工作者为了了解地下水的流向流速,确定水力传导系数、孔隙率、弥散系数,圈定地下水的污染范围和污染物扩散方向和速度,常常采用示踪方法。这种方法是利用示踪剂在地下水传递的途径与过程,对其结果进行分析以达到上述目的。
A good chemical tracer is essential in groundwater tracing.Ammonium molybdate was selected as the tracer,because it is nonposonous and stable,both physically and chemically.Mo has a low background vaJue and extremely low concentration levels of Mo can be determined rapidly by polarography in a mol/L H_(2)SO_(4)-3.5×10^(-4)mol/L benzilic acid-potassium chlorate medium.Karst water elements cause no interferences,and experiment shows that limestone and water sample containers do not adsorb Mo(Ⅵ).
