Description
Summary:The ability of the brown seaweed, Turbinaria conoides to absorb rhodamine B (RB) from aqueous solution was investigated in a batch system. The effects of various experimental parameters (e.g., morphology, initial dye concentration, temperature, and pH) were investigated and optimal experimental condition was ascertained. The results revealed that sorption capacity of T. conoides increased with increasing temperature, and decreasing initial dye concentration and pH. Sorption equilibrium studies using Langmuir and Freundlich models demonstrated that RB biosorption fitted well to the Langmuir isotherm. This study suggested that T. conoides can be used as a potential biosorbent for the removal of RB from wastewater.
