For the soak time experiment, we want to analyze for 2 things:
Water hyacinth and duckweed were selected as the adsorbents for this experiment.
For water hyacinth, two quick conclusions can be drawn for this experiment. First, over a longer period of time, it does drastically reduce the arsenic contamination. Second, it can be reused however; the adsorption level is less each time. More tests are needed to further understand this experiment.
