Applied Regression Analysis on Study of Biosorption Process of Gold Using Nanofiber Chitosan/PVA

Abstract:

Nanofiber has been widely used in various applications including agriculture, biomedical, pharmaceutical, and many other industries. In this study, nanofiber chitosan/PVA is utilized as an adsorbent for gold recovery due to its superior properties to adsorb metal ions from a solution. Adsorption isotherm was analyzed using the Langmuir and the Freundlich models. These models were used to evaluate the experimental data. In order to determine the more efficient models of gold recovery by using nanofiber chitosan/PVA, regression analysis methods were used to evaluate the data. Based on the result, we found that the Freundlich model was the best model for this study with parameters. This result also indicates that the biosorption process of gold in the nanofiber chitosan/PVA is a multilayer in heterogeneous surface and physical process.
