摘要	A magnetic nanomaterial for nitrite ion detection was demonstrated in the present study. This nanomaterial was prepared by grafting a rhodamine 6G derivative (denoted as Rh 6G-OH) into the channels of core-shell magnetic mesoporous silica nanospheres. The nanocomposite (denoted as Fe3O4@Rh 6G) showed large surface area and improved fluorescent performance to accumulate and recognize NO2-, and its superparamagnetic behavior played an important role in reusability. The fluorescent intensity decreased linearly along with the NO2- concentration in the range of 1-50 mu M, and the detection limit was estimated to be 0.8 mu M, which was much lower than the maximum limit of nitrite ion in drinking water (65 mu M) recommended by World Health Organization. Importantly, Fe3O4@Rh 6G could be magnetically collected and effectively reutilized after six test cycles.
