一、前言1972年,Davise等人将Orion和Corning交换剂分别制成PVC膜硝酸根电极,其电极性能与液膜电极基本类似,但测定下限不如相应的液膜电极Hans等人对PVC膜硝酸根电极做了不少工作,并提出了一个溶解度参数的新概念,对研制性能良好的PVC膜电极有指导意义。国内长春应化所用四烷基铵盐为活性材料、邻苯二甲酸二辛酯为增塑剂制成PVC膜硝酸根电极
I. Introduction In 1972, Davise and others made Orion and Corning exchangers were made of PVC membrane nitrate electrode, the electrode performance and liquid membrane electrode is basically similar, but the lower limit of determination than the corresponding liquid membrane electrode Hans et al. PVC membrane nitric acid A lot of work has been done on the root electrode, and a new concept of solubility parameter has been put forward to guide the development of PVC membrane electrode with good performance. Domestic Changchun should be used in the four alkyl ammonium salt as the active material, dioctyl phthalate plasticizer made of PVC membrane nitrate electrode
