CAS 7440-52-0: Soluzione standard di assorbimento atomico di erbio

Descrizione:
Soluzione standard di assorbimento atomico di erbio è una preparazione utilizzata principalmente in chimica analitica per la determinazione della concentrazione di erbio in vari campioni attraverso la spettroscopia di assorbimento atomico (AAS). L'erbio, con il simbolo chimico Er e il numero CAS 7440-52-0, è un elemento lantanoide noto per il suo aspetto metallico bianco argenteo ed è parte degli elementi delle terre rare. In forma di soluzione, l'erbio esiste tipicamente come ioni di erbio, spesso nello stato di ossidazione +3, che è la forma più stabile e comune nelle soluzioni acquose. La soluzione standard è caratterizzata dalla sua specifica concentrazione, che è cruciale per la calibrazione nell'analisi spettroscopica. Gli ioni di erbio mostrano lunghezze d'onda di assorbimento distinte, consentendo una quantificazione precisa in varie matrici, comprese le campioni ambientali e le applicazioni nella scienza dei materiali. La soluzione deve essere maneggiata con cura, attenendosi ai protocolli di sicurezza, poiché può contenere acidi o altri reagenti che possono essere pericolosi. Le condizioni di stoccaggio adeguate sono essenziali per mantenere l'integrità della soluzione e prevenire degradazione o contaminazione.

  • Erbium

    CAS:
    Erbium is a chemical element with atomic number 68. Erbium lasers are used to ablate tissue and as a light source for medical imaging. The laser light signal is generated by the decay of erbium-doped yttrium aluminum garnet (Er:YAG) rods, which emit infrared light at 2.94 μm wavelength. Er:YAG lasers have been used in the treatment of congestive heart failure and primary breast cancers. They have also been used to collect blood samples for analysis, as well as to measure intramolecular hydrogen bonds in proteins and DNA. Erbium has also been shown to inhibit mitochondrial membrane potential and oxidative injury, which may lead to apoptosis pathway activation and cell death.
