[Study on catalytic spectrophotometic determination of nitrite with catechol violet system].
A new sensitive method for the determination of trace nitrite was developed, based on nitrite as a catalyst. The optimum kinetic conditions were discussed and the concentration of nitrite was linear in the rang of 0.2-3.5 microg/10mL. The proposed method is simple, rapid, selective and convenient to determine nitrite in water and vegetables with good results.
