For this experiment, we want to analyze for 2 things:
Various experiments of contamination level vs. amount of adsorbent was conducted and the results are as follow:
The above graphs show us at 100ppb, it took 45 min for 1gr of water hyacinth to reduce the arsenic level down to ≤ 10μg/L. As you notice, the time also reduce as more water hyacinth was used.
At 200ppb with 2gr of water hyacinth, it also took 45 min to reduce the arsenic level down to ≤ 10μg/L.
At 300ppb, it took 45 min to reduce the arsenic level down to ≤ 10μg/L but 4gr of water hyacinth was needed.
Initial conclusion, an average of 45 min to reduce the arsenic level down to ≤ 10μg/L and more water hyacinth was needed as level of As contamination increases.
Eichhornia crassipes (commonly known as water hyacinth), is an aquatic plant native to the Amazon basin, and is often a highly problematic invasive species outside its native range. One of the fastest growing plants known, water hyacinth is a free-floating perennial aquatic plant (or hydrophyte) native to tropical and sub-tropical. In their native range these flowers are pollinated by long tongued bees and they can reproduce both sexually and clonally. The invasiveness of the hyacinth is related to its ability to clone itself and large patches are likely to all be part of the same genetic form.
