photocatalytic removal of o- nitro phenol fromwastewater by novel an eco-friendlymagneticnanoadsorbent

phenols are toxic organic compounds and which badly affects the flora and fauna of thebiosphere because phenols are persistent pollutant found in wastewater from many industries. in presentresearch article the photocatalytic removal of o-nitro phenol by synthesized magnetic nanoadsorbents(mna) carried out under photocatalytic reactor. the mna were synthesized by co-precipitation methodrequired short period of time. the photocatalytic reactor manually assembled in the laboratory. the u.virradiation found to be effective. the different parameters have been studied like initial concentration of onitrophenol, temperature, contact time, adsorbent dose and ph.the effective removal of o-nitro phenol bymna at optimum ph 1.5 to 2.5. the employed mna was characterized by sem (scanning electronmicroscopy), xrd (x-ray diffraction) and ftir (fourier transfer infrared spectroscopy). the presentremoval study well fitted for friendlich and langmuir adsorption isotherm. a kinetics and equilibrium studieswere also carried out by using mna. in this experimental research the desorption study of mna also showsgood results, reusability of mna were possible.
