【摘要】 <正> 为使PVC-AD电极能满足生活饮用水和地表水中阴离子表面活性剂含量(低至0.02mg/L)测定的要求,研究了电极在非Nernst区的响应,推导了新的响应方程,建立了定量分析方法,并进行了实际样品的测定。更多还原

【Abstract】 In this paper "a new response equation of Non-Nernst range of electrodes is derived and a quantitative analysis method is established. This method makes the electrode to be used to measure content of anionic surfactant in drinking water and surface water. The results show that the method would replace methylene blue colorimetric method.更多还原
