Abstract
The removal of copper and zinc from aqueous solution by adsorption on Ulva fasciata sp. was studied, as a function of contact time and pH of the solution. Adsorption of copper and zinc on U. fasciata sp. was compared. It was shown that U. fasciata sp. has high metal removal efficiency. The maximum adsorption capacity of U. fasciata sp. for copper and zinc was 26.88 and 13.5mg/g, respectively. The adsorption of copper and zinc on U. fasciata sp. was increased with increase in pH from 2 to 5 and decreased with increase in pH from 5 to 10. The Freundlich and Langmuir model can describe the adsorption equilibrium of copper and zinc on U. fasciata sp. The Freundlich and Langmuir constants for adsorption of copper and zinc on U. fasciata sp. were determined.Entities:
