Probe sonication synthesis of ZnFe2O4 NPs for the photocatalytic degradation of dyes and effect of treated wastewater on growth of plants

Today world is facing water pollution resulting from various sectors and presenting serious ecological concerns. The reusability of polluted water could be a promising study for the sustainable wastewater management strategy. In this, prepared ZnFe2O4 nano-photocatalyst was employed for photocatalytic degradation of organic dye pollutants namely Acid Red 88 (AR-88), Acid Orange 8 (AO 8) and Malachite Green (MG) under Sun light and UV irradiation. The UV-induced dye degraded wastewater samples were used to examine the green assessment towards the growth of Eleusine coracana (Finger millet) and Vigna unguiculata (Black eyed beans) plant. The results showed excellent plant growth in dye degraded wastewater sample noticed in the period of 3-5 days compared to pure water as control and with retard growth observed in dye solution. Thus, present research reported that the sustainability issues related to photodegradation of contaminated dye solution using prepared nano material was tested and efficiently using treated waste water in growing plants.
