Reusability of macroalgae (Euchema Spinosum) as biosorbent for dye removal

In this research, biosorption and desorption of Methylene Blue (MB) dye from red macroalga, Euchema Spinosum (E. Spinosum) were observed. Biosorption-desorption experiment were conducted to determine the most effective eluent for dye desorption and investigate the reusability of macroalgae as biosor...

Civil engineering (General) In this research, biosorption and desorption of Methylene Blue (MB) dye from red macroalga, Euchema Spinosum (E. Spinosum) were observed. Biosorption-desorption experiment were conducted to determine the most effective eluent for dye desorption and investigate the reusability of macroalgae as biosorbent.

As for the effect of the concentration, the result indicated that 1.0M HNO3 obtained higher desorption efficiency using different pH level (pH1-pH5) in which it decreased from 31.98% to 25.71%, rather than desorption efficiency of 0.5M HNO3 which is decreased from 27.42% to 25.43%.
