苦味酸根电极国内外均有报道。最近国外K.Hiiro等以生漆作为膜基质研制硝酸根、高氯酸根等漆膜电极,但制膜干燥条件难以掌握。我们以国产生漆和PVC作为膜基质材料,乙基紫-苦味酸缔合物为电活性物质,邻苯二甲酸二丁酯(DBP)为增塑剂,研制了苦味酸根涂碳电极。该电极具有膜质坚硬,平滑、光泽等特性。其线性范围为1×10~(-5 Picrate electrode has been reported both at home and abroad. Recently foreign K.Hiiro other lacquer as a substrate for the development of nitrate, perchlorate and other paint film electrode, but the film drying conditions difficult to grasp. We developed a picric acid coated carbon electrode by using domestic paint and PVC as the membrane matrix material, ethyl violet-picric acid association compound as the electroactive substance and dibutyl phthalate (DBP) as the plasticizer. The electrode has a hard film quality, smooth, shiny and so on. The linear range of 1 × 10 ~ (-5
