Descripción
Zn(II) and Cd(II) removal by biosorption using Undaria pinnatifida was studied in batch and dynamic systems. The kinetic uptake follows a pseudo second order rate equation indicating that the rate limiting step is a chemical reaction. The equilibrium data are described by the Langmuir isotherm in monocomponent solutions. In binary solutions, the Jain and Snowyink model shows that most of the active sites are exclusively accessible to cadmium ions without competition with the zinc ions. The dynamic studies show that the biosorbent has higher retention and affinity for Cd(II) than for Zn(II) in both monoand bi-component systems. SEM-EDX analysis indicates that the active sites are heterogeneously distributed on the cell wall surface. FT-IR spectrometry characterization shows that carboxylic groups and chemical groups containing N and S contribute to Zn(II) and Cd(II) uptake by U. pinnatifida. According to these results calcium-treated U. pinnatifida is a suitable adsorbent for Zn(II) and Cd(II) pollutants.
