Removal of Phenol byA. belladonna L.Hairy Root

Abstract

Phenolic compounds that present in the several industries are harmful and dangerous for human health. In this study we have studied the potential of Atropa belladonna hairy roots in phenol removal of wastewater. The optimal conditions for the removal process were evaluated using different phenol (10-500 mg.1(-1)) and H2O2 (1-15 Mm) concentrations. In the presence of H2O2, Roots were able to remove phenol concentrations up to 500 mg.1(-1). in the wide range of pH (4-9), reaching high removal efficiency. When roots were re-used for five consecutive cycles, phenol removal efficiency decreased from 98-62%, in the last cycle. After the removal process, the solutions were obtained from the experiment were estimated for their toxicity using a test with Lactaca sativa L. seeds. Results showed that the treated solution was less toxic than the parent solution.

Phytoremediation: green technology for improving aquatic and terrestrial environments

“…Plant species with the ability to produce hairy roots and suitable enzyme plays a main role in degradation of pollutants and several species have been investigated in literatures (Table 1). Furthermore, new plants such as garlic (Wang et al, 2015) and belladonna (Mazaheri and Piri, 2015) are cases of most recent studies. In a nutshell, focusing on optimization metabolisms and pollutants is one side of the future improvements in phytodegradation technique and the enhancement of pollutants uptake and degradation capacity is the other side of this precious green technology (Agostini et al, 2013).…”
