Abstract

Water pollution has become a massive problem over the years, causing harm to the aquatic and land ecosystems. One phenomenon that has contributed to the increase of water pollution has been the emergence of anionic surfactants, one of the most prominent ones being Sodium Dodecyl Sulfate (SDS), which is often used in hygiene products and manufacturing. Aquatic macrophytes like Pistia stratiotes and Ceratophyllum echinatum have been effective in their phytoremediation abilities of different types of pollution, most commonly in water samples. It was hypothesized that the P. stratiotes would be more effective in removing the pollutants from the sample than the other groups because the aquatic plant is known for being a hyperaccumulator that also has an extremely high tolerance to pollutants. The experimental groups were set up by acclimating the plant samples to distilled water for a week, then placing them in plastic totes with water and plant nutrient solution. 100 ppm of SDS were then put inside the plastic totes to start experimentation. A preliminary test was conducted where 100 ppm of SDS was put in a beaker of distilled water and fertilizer and dosed with methylene blue, then it was placed in the cuvette to observe the percent absorbance using the spectro vis. The data collected from the preliminary test was used as the control group data. The same test was conducted using the water samples from the plastic totes every three days for two weeks. After data collection, the one-way ANOVA test was conducted for significance. For the alpha value for 0.05, the ANOVA test found that there was enough evidence to reject the null hypothesis (F(3)=75.08 and p=0.0131). The results found that both Pistia stratiotes and Ceratophyllum echinatum were able to equally be effective against the contamination of the SDS in water samples. The Dunnett’s test was then conducted to determine which group was significant compared to the control group, which found that both experimental groups were statistically significant
