Adsorption of di-2-pyridyl ketone salicyloylhydrazone on Amberlite XAD-2 and XAD-7 resins: Characteristics and isotherms (Artigo de Periódico)

Freitas, Patrícia Antônio de Menezes; Iha, Koshun; Felinto, Maria Claudia França da Cunha; Suárez-Iha, Maria Encarnación Vázquez (Academic Press Inc., 2008)

The adsorption of DPKSH onto Amberlite XAD-2 (styrene resin) and XAD-7 (acrylic ester resin) has been investigated, at (25 ± 1) ° C and pH 4.7. The experimental equilibrium data were fitted to the Langmuir, Freundlich, and ...
Kinetic modeling of adsorption of di-2-pyridylketone salicyloylhydrazone on silica gel (Artigo de Periódico)

Freitas, Patrícia Antônio de Menezes; Iha, Koshun; Suárez-Iha, Maria Encarnación Vázquez (Academic Press Inc., 2007)

The kinetics of DPKSH (di-2-pyridylketone salicyloylhydrazone) adsorption onto silica gel has been investigated at (25 ± 1) ° C and pH 1 and 4.7. The kinetics of adsorption of DPKSH is discussed using three kinetic models, ...
