“…Zeolite synthesis is a multiphase reaction-crystallization process, usually involving at least one liquid phase and solid phases, both crystalline and amorphous phases, stemming from hydrogels such as aluminates and silicates and minerals, such as ash and calcined kaolin. Synthetic zeolites are formed at a temperature ranging from 80 ºC to 200 ºC (Cundy and Cox 2003;Viera et al, 2014). Due to their structural characteristics, zeolites have some unique properties that make them useful in many industrial applications, such as high specific surface area; pores, channels and cavities of molecular dimensions that impart different types of selectivity; high adsorption capacity, ease of separation of reactants and products; high thermal stability associated with higher Si/Al ratio and internal acidity, responsible for zeolite action as catalysts (Corma, 2003;Grecco and Rangel, 2013).…”

“…11 Já as zeólitas, consideradas aluminossilicatos hidratados, são bastante utilizadas em tratamento de efluentes, catálise, por apresentarem propriedades como: capacidade de troca iônica, adsorção de gases, capacidade de inchamento e adsorção elevada. 12,13 Além disso, pelo fato de serem atóxicas, as zeólitas são materiais com grande potencialidade de aplicação na área da saúde. As zeólitas são constituídas por tetraedros de SiO 4 e AlO 4 nos quais o átomo que liga um tetraedro ao outro é o oxigênio.…”

“…Pelo exposto, a utilização de zeólitas como cargas em nanocompósitos é bastante promissora. 12,13 Hidrogéis são polímeros hidrofílicos reticulados tridimensionalmente, sendo capazes de absorver elevada quantidade de água em sua estrutura sem se dissolver. 14 Quando intumescidos os hidrogéis se assemelham aos tecidos vivos pela quantidade de água existente em sua estrutura, além do que, o aspecto físico (elasticidade e maciez) reduz inflamações que são oriundas das reações com outras células.…”
