摘要
聚苯胺掺杂电位区(0.2～0.7V)循环伏安图能反映在聚苯腹膜内阴离子特性,Cl、ClO_4、SO^2_4和NO^-_3等简明阴离子在膜内可通过电位循环交换。Fe(CN)~3_6氧化还原型阴离子可掺入膜内,而呈明显的氧比还原峰(电位0.5,0.4V),聚苯胺膜可富集和分离Fe(CN)~3_4离子,对氨基苯酸磺基团阴离子,在正电位下,可与带正电荷骨架膜静电吸引,还可能有某种不可逆的化学作用。
The region of dope potential (0. 2 -0. 7 V vs. SCE) can reflect the an-ion property in polyaniline film. Some simple anion such as Cl- , ClO4- ,SO42- and NO3- can exchange in the film. The potential of peak Ⅰ,peak Ⅱ and the shape of peak Ⅲ can be used to characterize the exchange of anions. The ferricyanide-ferrocyanide redox type anion can dope into the film and form obvious redox peak (0. 5 V and 0. 4 V vs. SCE). Polyaniline film can collect and separate ferricy-anide-ferrocyanide anion. P-aminobenzene sulfonic acid can enter polyaniline 'bone'film with positive charge relying on strong electroststic attraction in positive potential ,they may take place an irreversible chemical reaction.
