TITLE:

REMOVAL OF MICROCYSTIN-LR BY ADSORPTION ON GRAPHENE OXIDE AND ACTIVATED CARBON

KEY WORDS:

SUMMARY:

The marked flowering of potentially toxin-producing cyanobacteria, especially in the semi-arid region of northeastern Brazil, has intensified concerns about the quality of treated water produced by water treatment plants and, in general, the currently installed treatment technologies are not efficient in removal of these micropollutants. Additional steps are necessary, in which adsorption appears as an alternative, both due to the possibility of recovering the adsorbent, as well as the ability to not generate by-products. In this context, the objective of this work is to evaluate the efficiency of removing microcystin-LR by the adsorption process using three different adsorbents: graphene oxide (GO), granulated activated carbon (GAC) and powdered activated carbon (PAC). The experimental phase will consist of batch and fixed bed column adsorption tests. In the end, it is intended to establish, for each tested adsorbent, the kinetic behavior of the adsorption, the adsorption balance by the isotherms and the maximum adsorptive capacity.
