Abstract
The aquatic plant Lemna minor (duckweed) was examined for its ability to sorb soluble lead from water under laboratory conditions. The use of biomass as a sorption medium provides a simple alternative separation technology. Laboratory-scale (700-mL) batch reactors containing soil-based sediments were used to expose L. minor to concentrations of 0.0, 5.0, and 10.0 mg/L of lead for 7 d. Overall removal amounts of 95% were observed, with 85% removal occurring within the first day. A sorption process model was developed based on a mass balance and a power law rate of sorption equation.
