Description

Applications
1-Nitroso-2-naphthol as a complexing agent for the on-line preconcentration of cobalt with FI-FAAS. 1-Nitroso-2-naphthol is the chelating ion-exchanger in the synthesis of alumina adsorbents that are of acidic, basic and neutral nature. It is used for the removal and preconcentration of Pb(II), Cu(II), Cr(III) from waste, as well as drinking water. It is also used in the preconcentration of cobalt using C(18) microcolumn with flow injection that is coupled to a flame atomic absorption spectrometry (FI-FAAS) system. 1-Nitroso-2-naphthol is used in the preparation of 1-nitroso-2-naphthol-sodium nitrite reagent.

Solubility
Insoluble in water.

Notes
Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Keep away from strong oxidizing agents, strong bases.
