The last of these factors is connected with the loss of mass during the deprotonation of polyaniline, and can thus be conveniently determined in situ by using a quartz microbalance. This is illustrated in the present paper, which concerns the determination of the weight fraction of acid in thin polyaniline films prepared by the chemical oxidation of aniline in the aqueous solutions of sulfuric and phosphoric acids.
