Biosorption of Cu (II) and Zn (II) with açaí endocarp Euterpe oleracea M. in contaminated aqueous solution

open access: yesActa Scientiarum: Technology, 2016
Current analysis investigates the capacity of the açaí endocarp (Euterpe oleracea M.) as a biosorbent for the removal of Cu2+ and Zn2+ in monoelementary water solutions. The best conditions for the ion adsorption process were pH of the solution at 4.0; 8

THERMODYNAMIC PARAMETERS FOR DISSOLVED GASES [PDF]

open access: yesProceedings of the National Academy of Sciences, 1969
In 1958 and subsequently we correlated properties of solutions of gases in liquids by using the “force constants,” ε/ k , and collision diameters, σ, which serve as parameters in equations for molecular pair potential energy such as that of Lennard-Jones or its variants.

Parameter Estimation Strategies in Thermodynamics [PDF]

open access: yesChemEngineering, 2019
Many thermodynamic models used in practice are at least partially empirical and thus require the determination of certain parameters using experimental data. However, due to the complexity of the models involved as well as the inhomogeneity of available data, a straightforward application of basic methods often does not yield a satisfactory result ...
