摘要
根据模拟水样与实际水样在电导率与全盐量的关系上有较好的吻合性 ,介绍了电导率法测定地表水中全盐量的方法。与传统重量法相比 ,具有快速、简便。
An conductometric method for determination of total salt content in ground water is described in this paper. Mixed solutions containing CaCl 2? MgSO 4? NaHCO 3 and KNO 3 in appropriate proportions are prepared and used as simulated water samples. It is found that a linear relationship between the total salt concentrations and values of conductivity of 50～300mg·L -1 of total salts, and the following regression equation is obtained: M =0 505 K +0.325( r =0.9999). The results obtained by this method are in consistency with those obtained by the conventional gravimetric method. The proposed method is proved to be more rapid, simple and accurate as compared with the gravimetric method.
