CAS 7440-52-0

Solução padrão de absorção atômica de érbio

Descrição:

Solução padrão de absorção atômica de érbio é uma preparação utilizada principalmente em química analítica para a determinação da concentração de érbio em várias amostras através da espectroscopia de absorção atômica (AAS). O érbio, com o símbolo químico Er e número CAS 7440-52-0, é um elemento lantânido conhecido por sua aparência metálica prateada e faz parte dos elementos de terras raras. Em forma de solução, o érbio geralmente existe como íons de érbio, muitas vezes no estado de oxidação +3, que é a forma mais estável e comum em soluções aquosas. A solução padrão é caracterizada por sua concentração específica, que é crucial para a calibração na análise espectroscópica. Os íons de érbio exibem comprimentos de onda de absorção distintos, permitindo uma quantificação precisa em várias matrizes, incluindo amostras ambientais e aplicações em ciência dos materiais. A solução deve ser manuseada com cuidado, aderindo aos protocolos de segurança, pois pode conter ácidos ou outros reagentes que podem ser perigosos. Condições de armazenamento adequadas são essenciais para manter a integridade da solução e prevenir degradação ou contaminação.
