Resumen
Foram feitos estudos comparativos entre quatro métodos para determinação de nitrato em amostras de águas naturais, colhidas em dez poços na cidade de São Paulo. Procurou-se destacar os problemas operacionais e os possíveis interferentes para cada método. Com base nos resultados obtidos, foi sugerido o método do ácido fcnoldissulfônico como o mais apropriado para o uso em análises de rotina de amostras de água.
