In this text, potentiometric titration has been developed for determining epoxy and amino on surface modified nanosilicas. It is based on the sensitive response versus pH of prepared poly(p-nitroaniline) modified Pt electrode (PME) as indicator electrode. The process of electropolymerizing p-nitroaniline, the response versus pH and the performance of PME have been discussed in detail. Results among acid–base titrations in aqueous solution confirmed the reliability and accuracy of PME as indicator electrode. Especially, the PME was employed for determining epoxy and amino groups on surface modified nanosilicas with good results, which not only provided important information of the amounts of epoxy and amino groups on nanosilicas but also supplied technique supports for determining epoxy and amino on other similar category products.
