Abstract
Introduction. Environmental contamination produced by the disposal of effluents from textile
industries, encourages researchers to continue their search for the removal of this dyes
in waste water. Objective. To compare the effect both an artchoke extract with peroxidase
activity and a conventional method, hydrogen peroxide, had in the discoloration of an effluent
from a textile industry. Materials and Methods. As a sample, a mixture of direct, disperse
and acid dyes was used. They were all from a textile industry located in an Antioquian municiple.
The artchoke´s extract and the hydrogen peroxide, and a mixture of both 1:1 were used as
degradation agents. Absorbance measures were made by the use of a UV-Vis spectrophotometer.
Results. For the treatment of the sample with artchoke extract, peroxide and the mixture
of both, there is an absorbance reduction of 21.03%, 12.32%, 22.70%, respectively, at 486 nm
and of 17.13 %, 16.43%, 28.54% at 598 nm. Conclusion. The artchoke extract provides a
discoloration similar to that of the hydrogen peroxide, becoming an alternative in comparison
to the use of conventional methods that bring environmental problems.
