Mobile analysis with potentiometric sensors is well suited for field measurements. Ion-selective electrodes (ISE) based on polymeric membranes for in-situ determination of nitrate and ammonium contents in ground water, drinking water and surface water have been developed. The ISE are integrated in a multisensor module (MSM) for monitoring these ions over longer time intervals. The receptor is a PVC-membrane with tridodecylammonium nitrate (TDDA) for nitrate- and nonactine for ammonium-electrodes as ionophores. As plasticizer dibutylphthalate (DBT) was used. The main parameters for assessing the efficiency of these ISE are presented.
使用电位传感器进行移动分析非常适合现场测量。已经开发出基于聚合物膜的离子选择性电极（ISE），用于原位测定地下水、饮用水和地表水中的硝酸盐和铵含量。ISE集成在一个多传感器模块（MSM）中，用于在较长时间间隔内监测这些离子。受体是一种PVC膜，其中硝酸三（十二烷基）铵（TDDA）用于硝酸盐电极，诺卡菌素用于铵电极作为离子载体。使用邻苯二甲酸二丁酯（DBT）作为增塑剂。介绍了评估这些ISE效率的主要参数。
