Abstract

A new type of magnetic polymer microspheres containing methylamino groups on the surface was synthesized. It can be reacted with nitrite to produce electroactive <i>N</i>-nitroso compound. On reduction of this derivative collected on the magnetic electrode, nitrite can be determined. Under optimum conditions, the peak potential (<i>E</i><sub>p</sub>) of the derivative is -0.72 V (<i>vs</i> Ag/AgCl). Nitrite in the range 1-800 μg l<sup>-1</sup> can be determined, the detection limit being 0.5 μg l<sup>-1</sup>. The relative standard deviation for determination of 100 μg l<sup>-1</sup> nitrite was 1.96%. The method was used in the determination of nitrite in water samples with satisfactory results. <p>
