Abstract

The effect of waste water containing Pb, variations to plant life spans, and variations of soil has been studied to examine the absorption rate of Pb in Cattail by using Michaelis-Menten equation. The plants and sediments removed each four days to examine the Pb content in root, rhizome, and leaf of plant. The experiment showed that the growth rate of  3 months old Cattail using soil and sand were  decreased but on the contrary in  absorption rate, with Vmax at 22,573 mg/kg/day and Km at 3,562 l/d. The life spans of plant, waste concentrations and soil has influenced the uptake rate of Pb in plant significantly.
