PreparaÃÃo de carvÃo ativado a partir de borra de cafÃ: uso como adsorvente e como suporte catalÃtico para a remoÃÃo de poluentes orgÃnicos em meio aquoso. / Activated carbon production by spent coffee grounds: use as adsorbent and catalytic support for organic pollutants removal from aqueous medium
In this work, the preparation of activated carbons (AC) using spent coffee grounds and three activating agents CO2 (AC CO2), water vapor (AC H2O) and K2CO3 (ACK) were evaluated. These AC showed microporous nature with high surface area, except for AC CO2. These materials, as well the commercial AC (ACC) were tested as adorvents for the organic contaminant mo
