Remoción de amoxicilina de aguas contaminadas por electrocoagulación

Abstract

The objective of the investigation was to determine the degree
of reduction of amoxicillin in contaminated water, through the
electrocoagulation process. The electrocoagulation cell worked
with stainless steel and aluminum electrodes (cathode and anode
respectively), for a capacity of 1 liter of contaminated water. The
process consisted of supplying electric current through the electrodes,
causing the suspended particles to lose their stability and thus form
agglomerates that floated towards the surface of the water, as well
as precipitates that fell towards the base of the electrocoagulation
cell. For this reason, the research is of an applicative type with
a quantitative approach and experimental design. For which 9
experiments were carried out where they worked with the variables
of Voltage (7, 9 and 11V) and pH (5, 6.5 and 8), achieving removals
between 47.2 mg/L to 7.9 mg/L, resulting that the two variables
in study were significant. It was observed that under conditions of pH = 5 and V = 11V,
the highest removal of the Chemical Oxygen Demand (% CODe) 84.56%
was achieved; therefore, it is possible to apply electrocoagulation
treatment to water contaminated with amoxicillin.
