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.
存在于多个行业中的酚类化合物对人体健康有害且危险。在本研究中,我们研究了颠茄毛状根在去除废水中苯酚方面的潜力。使用不同的苯酚(10 - 500 mg·L⁻¹)和过氧化氢(1 - 15 mM)浓度评估了去除过程的最佳条件。在过氧化氢存在的情况下,根能够在较宽的pH范围(4 - 9)内去除高达500 mg·L⁻¹的苯酚浓度,达到较高的去除效率。当根连续重复使用五个循环时,在最后一个循环中苯酚去除效率从98%降至62%。去除过程后,使用莴苣种子试验对实验获得的溶液进行毒性评估。结果表明,处理后的溶液毒性低于原液。
