The adsorption of Reactive Orange 16 and Basic Blue 3 from aqueous solution using quaternized blue swimmer crab carapace

The crab carapace is a waste which cannot be decomposed. This waste was used to remove the Reactive Orange 16 (RO16) and Basic Blue 3 (BB3) from aqueous solution at different operational parameters such as pH, mass load, the concentrations of dye and the temperature. The crab collected was modified...
