Abstract：

A　new　sensor　material　for　monitoring　pH　in　aqueous　solutions　is　described.　It　is　based　on　lipophilic　ion　pairs　consisting　of　an　anionic　pH　indicator　Bromocresol　Green　and　a　quaternary　ammonium　cation　cetyltrimethylammonium.　The　ion　pairs　are　homogeneously　distributed　inside　the　plasticized　PVC　membrane.　The　change　of　pH　in　an　aqueous　solution　causes　the　change　of　optical　property　of　the　indicator　immobilized　on　the　plasticized　PVC　membrane.　The　plasticized　PVC　membrane　is　sensitive　in　a　pH　range　from　4.0　to　6.0.
