Production of Activated Carbon from Agroindustrial Residues and Application in the Treatment of Desalinator Reject | Chapter 07 | Current Perspectives to Environment and Climate Change Vol. 2
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.
