Um estudo comparativo entre o peso relativo e o peso para os métodos da soma dos pesos e o produto dos pesos no método AHP na seleção do melhor material para a adsorção de corantes de águas residuárias

In recently years the adsorption using alternatives materials such as organic plants and remains materials has been used and has had a lot of attention of the researchers on the subject. In this work, we have studied the adsorption process using angelim sawdust, rice husk and MDF. This work is an attempt to identify the best material for the adsorption of dye wastewater. For this purpose, the analytical hierarchy process was utilized to select the best material for the adsorption and was also considered a comparison between relative weight and weight for the following methods, sum weight and product weight method. The selection material in this study was made for wastewater contend dye in solution and four factors, absorptivity (ABS), concentration of adsorbed dye (NAS), turbidity (TUR), time of adsorption (TAS).
