Sobre IBD

È stato stabilito un nuovo metodo per la determinazione dei ritardanti di fiamma estraibili da campioni di prova in tessuto, schiuma, pelle e plastica. I ritardanti di fiamma sono stati estratti con toluene dai campioni di prova utilizzando un’estrazione assistita da ultrasuoni con un tempo di estrazione di 60 minuti a 60 ºC. I ritardanti di fiamma sono stati separati su una colonna DB-XLB utilizzando la spettrometria di massa gascromatografica (GC-MS) con elio (99,9%) come gas di trasporto. Per l’analita target sono stati selezionati uno ione target e due ioni qualificatori in modalità SIM/SCAN. Sono stati ottimizzati i parametri di pretrattamento, tra cui il tipo di estrattore, il metodo di estrazione e il tempo di estrazione. In condizioni ottimizzate, i recuperi dei composti target variavano dal 90 al 100,8%. L’intervallo di lavoro della curva di calibrazione era compreso tra 0,25 e 5,0 mg L-1 con un valore di regressione pari a 0,996-0,998. La deviazione standard relativa (RSD) è stata rispettivamente
