Synthesis and application of a new carboxylated cellulose derivative. Part III:...
Teodoro, Filipe Simões; Elias, Megg Madonyk Cota; Ferreira, Gabriel Max Dias; Adarme, Oscar Fernando Herrera; Savedra, Ranylson Marcello LealIn the third part of this series of studies, the adsorption of the basic textile dyes auramine-O (AO) and safranin-T (ST) on a carboxylated cellulose derivative (CTA) were evaluated in mono- and bi-component spiked aqueous solutions. Adsorption studies were developed as a function of solution pH, contact time, and initial dye concentration. Adsorption kinetic data were modeled by monocomponent kinetic models of...

Savedra, Ranylson Marcello LealCoordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); Compact models of ionized and nonionized Langmuir monolayers of stearic acid adsorbed on the water were simulated by means of atomistic molecular dynamics. The electrostatic, structural and dynamic properties of the molecules of models were studied throughout time evaluating the calculated trajectory. The structural analyses indicate a signifi...
