Özet
This study focuses on the removal of commercial Acid Yellow 2G and Indigo dyes by using biosorbent Hawaiian Spirulina pacifica (HSP). It studies the effects of pH, the initial dye concentration, the biosorbent dose and the agitation speed and temperature, on the removal of dyes. Thermodynamic parameters indicated the exothermic and spontaneous characteristics of biosorption. Langmuir, Freundlich and Temkin adsorption isotherms were applied to examine the efficiency of HSP. Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) images proved moderate adsorption of dyes onto HSP. The results shows that this commercial, ecological, low-cost and natural nutrient biosorbent may be useful for the removal of toxic and hazardous textile dyes from aqueous solutions.
