Absorption of Dyestuff using Cuttlebone

Abstract

The main aim of this research is to studied the optimal conditions (initial concentration and absorption time) affected the absorption of Malachite Green (MG) dyestuff by using cuttlebone. The sample was characterized by Fourier-transform infrared spectroscopy (FT-IR) and scanning electron microscope (SEM). From the results, it was found that the efficiency of cuttlebone which adsorbed 100 ppm and 150 ppm of MG dyestuff reach to 99% in 15 minutes. FT-IR result revealed the cuttlebone has structure like cellulose, showing the functional groups such as: -OH group at 3374.76 cm^-1 and 1444.79 cm^-1, -NH amide group at 852.29 cm^-1. The SEM result showed the roughness and agglomeration morphology of the cuttlebone and let high absorptivity. The knowledge from this research is using to apply for waste water treatment.
