摘要：
Polyaniline-polyvinyl alcohol (PAPVA) colloids consisting of polyaniline (PA) and polyvinyl alcohol (PVA) were prepared. This colloid is electrochemically active and can adsorb various anions. The adsorption occurs electro-chemically or chemically. The selectivity sequence of the PAPVA colloid toward monovalent anions was SCN-> ClO4−>BF4−>Br− ≫ Cl−≈CF3COO−≫C6H5SO3−. Adsorption ability of the PAPVA colloid toward each anion was enhanced when large anions such as G6H5SO3−, were doped into the colloid.
