摘要
We present here anion-exchange nanospheres as novel titration reagents for anions. The nanospheres contain a lipophilic cation for which the counterion is initially Cl-. Ion exchange takes place between Cl- in the nanospheres and a more lipophilic anion in the sample, such as ClO4- and NO3-. Consecutive titration in the same sample solution for ClO4- and NO3- were demonstrated. As an application, the concentration of NO3- in spinach was successfully determined using this method.
