Sobre IBD

Questo libro tratta l’uso di materiali adsorbenti modificati a base di bentonite per il trattamento delle acque contaminate da composti organici fenolici. Vengono esplorati tre tipi di modifica: attivazione acida mediante H3PO4, funzionalizzazione mediante chitosano e intercalazione di tensioattivi (CTAB). I materiali così ottenuti sono caratterizzati con varie tecniche (XRD, FTIR, SEM-EDX, TGA-DTA) per analizzare i cambiamenti strutturali e morfologici. L’adsorbimento è studiato in funzione di diversi parametri (pH, tempo, temperatura, concentrazione) e i risultati sono interpretati mediante modelli cinetici, isotermici e termodinamici. I dati sperimentali mostrano un significativo miglioramento della capacità di adsorbimento dopo la modifica. I test di rigenerazione confermano la stabilità e la riutilizzabilità dei materiali. Questo lavoro apre prospettive per l’uso di questi materiali in applicazioni sostenibili di trattamento delle acque.
