Selective electrochemical molecular recognition of benzenediol isomers using molecularly imprinted TiO2 film electrodes

In this paper, selective recognition of benzenediol isomers was studied using molecularly imprinted TiO2 film formed on a graphitic electrode. The imprinting process was investigated in detail using IR. The electrode process for p-hydroquinone follows a ErCr mechanism. The cavities formed by p-phthalic acid have good selectivity toward p-hydroquinone among the isomers. The complex ratio between p-hydroquinone and binding sites was estimated to …
