Removal of Tartrazine Dye Using Kyllinga Brevifolia Extract And Silver Nanoparticles As Catalysts

Abstract

The objective of this study was to determine the effectiveness of kyllinga brevifolia (KB) with silver nanoparticles (AgNPs) as catalysts in the removal of tartrazine dye. The experiment was carried out in batch mode. Different parameter such as temperature, initial concentration, contact time and pH were studied. It was found that the equilibrium was achieved in 20 min and the optimum pH was 2. The removal of dye highest at 80 ̊C, which is 64%. From an initial concentration of 60 ppm and onwards, the removal efficiency of dye was the most (62.34%) when compared to other intial concentrations. The use of a AgNPs as catalyst increases the removal efficiency 20.68% more effective than without a catalyst. Significant of this study is to show the effect of AgNPs as catalyst in tartrazine dye removal from wastewater.
