Abstract

um sensor óptico de nitrato possui um processador de sinal ou módulo de processamento de sinal configurado para: receber sinalização que contém informação sobre uma concentração de nitrato dissolvido na água com base em uma primeira absorbância óptica de luz uv situada em 229 nm, e que contém informação também sobre uma matéria orgânica dissolvida (mod) detectada na água com base em uma segunda absorbância óptica de luz uv associada, situada em uma faixa de 250 nm a 275 nm; e determinar a sinalização correspondente que contém informação sobre uma concentração corrigida de nitrato dissolvido na água por meio da compensação da concentração de nitrato para a mod detectada na água com base na sinalização recebida.
