Phytoremediation of a dissolved nitrate by using Louisiana Irises (Iris Professor Claude).

The purpose of this experiment is to determine if the Louisiana Iris (Iris Professor Claude) can be used for Phytoremediation of Nitrates in contaminated waterways. It was hypothesized that the plants would remove more than 35% of the Nitrate concentrations as N[O.sub.3]. The procedure used for this experiment was the sub-irrigation method. Seven plants were put into 4 fish tanks. Two plants each in 3 tanks and 1 plant in the fourth tank. Different ppm of nitrate was added to each tank, 100ppmN, to tank A, 250ppmN, to tank B, and 500ppmN to tank C, and tank D was the control. The findings did not support the experimental hypothesis. The ppm in each tank did not considerably change. One variable that did change was the health of the plants. There was a drastic change in most of the plant health color, leaf numbers, and root growth of plants grown in Nitrate solution. The control variable remained the same.
