Tiras de teste de nitrato\/nitrito MN<\/h2>\n

Para que se medem nitrato e nitrito?<\/h3>\n

Nitrato (NO\u2083\u207b) e nitrito (NO\u2082\u207b) s\u00e3o compostos nitrogenados importantes na an\u00e1lise da \u00e1gua. O valor-limite do nitrato na \u00e1gua pot\u00e1vel \u00e9 de 50 mg\/l<\/strong>, o do nitrito de 0,5 mg\/l (regulamento alem\u00e3o da \u00e1gua pot\u00e1vel). Ambos os par\u00e2metros precisam ser monitorados regularmente.<\/p>\n

O nitrato<\/strong> chega \u00e0s \u00e1guas subterr\u00e2neas e superficiais principalmente pela fertiliza\u00e7\u00e3o agr\u00edcola e pelas \u00e1guas residuais. Concentra\u00e7\u00f5es elevadas de nitrato podem ser nocivas para lactentes (metemoglobinemia) e indicam uma contamina\u00e7\u00e3o da bacia de capta\u00e7\u00e3o.<\/p>\n

O nitrito<\/strong> forma-se como produto intermedi\u00e1rio na transforma\u00e7\u00e3o bacteriana do am\u00f4nio em nitrato (nitrifica\u00e7\u00e3o) e \u00e9 mais t\u00f3xico que o nitrato. Em tubula\u00e7\u00f5es de \u00e1gua pot\u00e1vel, o nitrito pode se formar por estagna\u00e7\u00e3o e atividade bacteriana.<\/p>\n

As tiras de teste de nitrato\/nitrito MN determinam ambos os par\u00e2metros simultaneamente em uma \u00fanica medi\u00e7\u00e3o \u2013 ideal para um teste de orienta\u00e7\u00e3o r\u00e1pido.<\/p>\n

Como funcionam as tiras de teste?<\/h3>\n

As tiras possuem duas zonas de rea\u00e7\u00e3o separadas: uma para o nitrato e outra para o nitrito. Ambas as zonas mudam de cor ao serem mergulhadas na amostra conforme a respectiva concentra\u00e7\u00e3o. Comparando a cor com a escala impressa, ambos os valores s\u00e3o lidos simultaneamente.<\/p>\n

Leitura do nitrato:<\/strong> escala de cores com passos 0 \/ 10 \/ 25 \/ 50 \/ 100 \/ 250 \/ 500 mg\/l NO\u2083\u207b.
\nLeitura do nitrito:<\/strong> escala de cores com passos 0 \/ 1 \/ 5 \/ 10 \/ 20 \/ 40 \/ 80 mg\/l NO\u2082\u207b.<\/p>\n

Vantagens das tiras de teste MN<\/h3>\n
    \n
  • Determinar dois par\u00e2metros de uma vez\n

    Nitrato E nitrito em uma \u00fanica medi\u00e7\u00e3o \u2013 pr\u00e1tico e econ\u00f4mico em tempo<\/p>\n<\/li>\n

  • Medi\u00e7\u00e3o r\u00e1pida em aprox. 1 minuto\n

    Resultados imediatos sem reagentes ou aparelhos<\/p>\n<\/li>\n

  • 100 determina\u00e7\u00f5es por frasco\n

    Especialmente econ\u00f4mico para controles regulares<\/p>\n<\/li>\n

  • Ampla faixa de medi\u00e7\u00e3o\n

    Nitrato 0-500 mg\/l, nitrito 0-80 mg\/l \u2013 cobre todas as faixas relevantes na pr\u00e1tica<\/p>\n<\/li>\n

  • N\u00e3o requer reagentes\n
