| Descripción : | Emerging contaminants (EC) are compounds of different origin and chemical nature, their presence in the environment generates concern about their possible effects on the ecosystem and human and animal health. In this work, phytoremediation was studied as a possible tool for the treatment of contaminated water. The efficiency in the removal of acetaminophen and ciprofloxacin using Chrysopogon zizanioides and Eichhornia crassipes was determined under controlled conditions. The time and the optimal concentration of the EC with the best removal rates was established; and different physiological parameters were evaluated. For this, a completely randomized block design was proposed, where Chrysopogon zizanioides appears as block 1 and Eichhornia crassipes as block 2. Each plant species was adapted and multiplied in water pools with NPK solution applications. In addition, calibration curves for each drug were made using UV visible spectrophotometry; technique that was used to quantify the contaminant in each treatment. In block 1, a removal of 55.77 percent for T1 and 86.82 percent for T10 was evidenced for acetaminophen and ciprofloxacin respectively. On the other hand, in block 2, removals greater than 40 percent was achieved for T2 and T5, at 96 hours for acetaminophen. While for ciprofloxacin, removals greater than 80 percent were obtained, for T11 and T14, in the first 24 hours, while at 96 hours the removal overpassed 92 percent. In the same way, T1, T4, T10 and T13 present the highest performance values for block 1. While for block 2, they do T2, T5, T8, T14 and T17. In addition, it is observed that block 2 has higher yields than block 1. The analysis of physiological parameters showed that the evaluated pollutants do not have a direct effect on the variables of wet weight, dry weight and chlorophyll in block 1. The same occurs with block 2, except for the contaminant ciprofloxacin, which causes a clear decrease in the levels of the chlorophyll variable. In conclusion, phytoremediation could be an alternative for the removal of pharmacological contaminants, since it presents more advantages in terms of investment and response time than conventional methods of water treatment. |
