Subsurface Flow Phytoremediation Using Barley Plants for Water Recovery from Kerosene-Contaminated Water: Effect of Kerosene Concentration and Removal Kinetics

A phytoremediation experiment was carried out with kerosene as a model for total petroleum hydrocarbons. constructed wetland of barley exposed to pollutants at varying concentrations (1, 2, and 3% v/v) in subsurface flow (SSF) system. After period 42 days exposure, it found that the average ability eliminate ranged from 56.5% 61.2%, highest removal obtained concentration 1% v/v. The analysis initial allowed kinetics be fitted Grau model, which closer than zero order, first or second order kinetic models. experimental study showed plant designed system would have great potential reclamation kerosene-contaminated water.
