Abstract
Non-viable biomass of the aquatic fern, Azolla filiculoides, removed u p to 93 mg lead/g biomass from solution. Lead removal varied from 30% of the initial lead concentration at pH 1.5 to approximately 95% at pH values of 3.5 and 4.5. Lead removal decreased to 30% of the initial l ead concentration if the lead concentration was initially over 400 mg/ l. Lead removal remained at approximately 90% between 10 degrees C and 50 degrees C. Biomass concentration (4-8 mg/l) had little effect on l ead removal.
