Abstract

Residues of agroindustrial origin can be used for various purposes, including the production of activated carbon. In order to conduct the experiment, residual biomass of Cocos nucifera-C and grape marc-B were used at the doses corresponding to 100C/0B, 75C/25B, 50C/50B, 25C/75B and 0C/100B. The appropriate operating ranges for the production of activated carbon were identified and an experiment was carried out with a full factorial design, type 32, with three replicates and a control. The activated carbon produced was in contact with the desalinator reject for 30, 60, 120 and 180 minutes, after which the extracts were physico-chemically analyzed. The data were submitted to statistical analysis, using Statistic software, with a percentage reduction in the characteristics evaluated: pH (13.2), electrical conductivity (1), sodium (4.7), potassium (35.6), calcium (3.2), magnesium (zero) and chloride (18.2), indicating the mixture of coconut fiber and grape marc in 50C/50B ratio as being the most promising in the adsorption of the chemical elements of the reject, when in contact for up to an hour.
