The harsh Pernambuco produces high volumes of liquid effluents containing dyes in the textile production, this pigmentation prevents the photosynthesis of the aquatic flora and are considered toxic, to treat these effluents there are several processes, being the adsorption a very effective method. This work evaluated the absorptive capacity of the activated carbon produced from the potato peel in a synthetic effluent containing the Direct Black 22 dye. The finite bath system was operated with a two-factor agitation (0 rpm, 100 rpm, 200 rpm) and the dye concentration (0.02 g / L, 0.05 g / L and 0.08 g / L) maintaining 5 h as the equilibrium time. The removal of Direct Black 22, remained between 55% and 98.75%, having a higher percentage of removal using higher concentration (0.08 g / L) and agitation (200 rpm).
