Research Plan:

A.  Statement of the Problem:

            This scientific research will be conducted in order to investigate the purification properties of the three aquatic plants, Monochoria vaginalis, Sphenoclea zeylanica, and Azolla nilotica.

            More specifically, it aims to answer the following questions:

a. Will the compound metal be recovered using the three different specimens of aquatic plants?

b. What indicator will show that the plants absorb the metals in the metal solution?

c. Which of the metals will bioaccumulate most in the plant’s structure?

d. Which of the following plants is the most effective in bioaccumulating metals in the metal solution?

B. Hypothesis

            The three aquatic plants, Monochoria vaginalis, Sphenoclea zeylanica, and Azolla nilotica, will absorb the metal compound from the solutions at different percentage rate to purify the solution.

C. Description in detail of method or procedures

            The researchers will use double beam balance to weigh the gathered specimens of Monochoria vaginalis, Sphenoclea zeylanica, and Azolla nilotica.  Furthermore, four 500 and 250ml. beaker will be used as the container for the 100ml. solution of compound metals.  The digital pH meter will also be used to determine the pH level of each solution.

            After the experiment, tests, and replicates, filter paper will be used to filter the leftover of the plants in the metal solution.   The double beam balance and the digital pH meter will be used again to determine the changes in the solution brought by the aquatic plants; moreover, it is for the researchers to investigate whether the plants exhibit the same ability to biaccumulate metals at the same time and also for the group to determine the rate of percentage of the plants in purifying the water.
