Fig. 4 FTIR results of produced biosurfactant
Sample-1: (The untreated waste water) shows the presence of Chromium and Lead
in the concentrations of 4.71 ppm and 4.55 ppm respectively. As the result both the
heavy metals are almost detected at same concentrations.
Sample-2: (100 µl of biosurfactant treated waste water) after the treatment the
concentration of chromium was reduced from 4.91 ppm to 3.55 ppm. Also the concentration of lead after the treatment with biosurfactant was reduced from 4.55 ppm to
2.28 ppm respectively (Fig. 5).
