ABSTRACT: The study
was carried out to evaluate six different hydrophytes which were tested
associated by twos: 1) Lemna gibba and Ceratophyllum demersum, 2) Berula erecta and Lemna gibba, 3) Polygonum
punctatum and Hydrocotyle
ranunculoides, and 4) Polygonum
punctatum and Azolla filiculoides,
for the purpose of removing nitrate from the water of Reyes Aztecas Lake, which
is located southeast of Mexico City in Tláhuac District, Mexico D.F. The
average of removal efficiency was obtained in relation to the different
hydrophytes associations based on five sampling stations. The statistical
analysis revealed that there were no significant differences among hydrophytes,
all show remarkable ability to remove nitrate in water.
