PHYTOREMEDIATION OF FLUORIDE-CONTAMINATED WATER BY Landoltia punctata

Fluorine is released into the water environment naturally or by anthropogenic activities. promotes health benefits at low concentrations, but it adverse effects ranging from fluorosis to carcinogenic problems high concentrations. Although fluorine removal can occur through processes such as adsorption, reverse osmosis, and electrodialysis, phytoremediation emerges an accessible environmentally friendly treatment. This research aimed study potential of Landoltia punctata for treating contaminated with ion (fluoride). The central composite rotatable design was used assess effect three variables in process: pH 5 9; phosphate concentration 0 10 mg L−1; nitrate 800 L−1. plants were exposed a fluoride initial L-1 3L-vessels that also included Clark's solution period days. Experimentally, up 21% observed supplied fluoride. Values order 30% removed mass be predicted obtained model. promising candidate fluoride-contaminated waters.
