摘要：

We report a simple method by which the neutralization point in the Boehm titration can be easily determined without going through a pre-screening process to remove the effect of atmospheric carbon dioxide (CO2). The proposed method is based on the principle that the equivalence and the corresponding neutralization point of the reaction bases remains unchanged regardless of the dissolution of CO2 in the reaction bases. This method was used to measure the surface functionality of acid-treated multi-walled carbon nanotubes with high precision. (C) 2011 Elsevier Ltd. All rights reserved.
