摘要: The removal of Cr(VI) from wastewater by Lemna minor was studied both at laboratory and pilot scale. Laboratory tests were conducted under different conditions initial concentration (0.5 2.0 mg/l) temperature (285 291 K). Batch experiments carried out during 16 days in which the chromium concentrations, biomass measured. Data used to characterize biouptake capacity biomass; results showed that it increases with when Cr decreases. process could be fitted an equation, a correlation coefficient 0.98. assessed using data variation respect time; this allowed obtaining constant parameters applied mathematical model for assessment duckweed systems scale plant.
