Using the magnetic and nanotechnology in the treatment of wastewater and its effect on the growth and yield Vigna radiata L

Abstract

Abstract Two laboratory experiments were conducted, the first to obtain the best concentration of nanomaterial’s used Fe3O4 in removing heavy elements from wastewater, and the concentrations were (50, 100, 150, 200, 250) mg.L−1, and the concentration was chosen 100 mg. L−1 was the best concentration after achieving the highest rate of removal of heavy elements from wastewater, and the second to test the effect of treated nanoparticles and magnetic particles, and the interference between them in the germination rate of livestock seeds used as a biomarker in sterile plastic plates at a rate of three iterations per treatment and experiment parameters were water treatment River T0 and T1 treatment untreated wastewater and T2 wastewater treatment with nanomaterial’s treatment, T3 magnetic treatment wastewater treatment and T4 treatment, which overlap between the two treatments, and T3 and T4 treatments achieved the highest germination rate of 100% for the two treatments. A field experiment was conducted in Al-Mu’tasim area, 20 km south of Samarra - Salah Al-Din area located at latitude 3771307 and longitude 413224 in July 2019 to see the effect of experiment treatments on some characteristics of the growth of Vigna radiata L. plants, and the results showed that the T4 treatment significantly exceeded all treatment treatments in Some plant growth characteristics such as plant height, leaf area, dry vegetable weight, dry root weight and percentage (43.00, 14.60, 77.95, 71.87)% for trait respectively when compared to T1 treatment which achieved lower mean for the mentioned traits.
