Uso da biomassa de casca de banana na remoção de cádmio em solução aquosa

Abstract

The use of substrates in aqueous solutions treatment containing heavy metals has been extensively investigated. In this scenario, studies to evaluate the banana peel potential in the adsorption of metals have grown. The adsorption process using biosorbents has been highlighted, therefore, the present work investigated the banana peel flour potential as an alternative material for the cadmium (Cd) removal in aqueous solutions. Using the batch method, the adsorbent mass influence and the concentration of the Cd solution at pH 3 was investigated. The results were obtained by atomic absorption spectrometry equipment, and later analyzed by the R statistical system. The adsorption percentage for Cd ranged from 22.86 to 75.20% with standard deviations from 0.0057 to 0.04 and the coefficient of variation was between 4.22 and 26.33%. Was concluded that the banana peel has a high potential for adsorption of Cd in aqueous solution. Can be observed satisfactory results and are in agreement with the literature
