Removal of metals from water of Yarinacocha Lagoon with activated carbon from cocoa pod husks

ABSTRACT The problem addressed is the contamination of Yarinacocha Lagoon water by heavy metals and poor use agricultural residues. It was manufactured activated carbon from cocoa (Theobroma cacao L.) pod husks determined its adsorbent effect in removing polluting waters Lagoon. response surface methodology applied with factorial designs 33 32, three replicates to optimize obtaining measure effectiveness metal removal. modeling pyrolysis process resulted 17.27 g 295.72 dry husks, optimal following parameters: 150 °C as activation temperature, 450 carbonization 2.5 hours modification time. This effective removal pollutant (aluminum: 91.43%, copper: 75%, iron: 58.33% zinc: 58.33%), samples demonstrating that it possible manufacture an potential remove
