Abstract : In this study, nanoscale zero-valent iron 10 (NZVI) particles have been used for phosphate recovery 11 from aqueous solutions. The bioavailability of the phosphate 12 sorbed onto NZVI particles was determined by using spinach 13 (Spinacia oleracea) and algae (Selenastrum capricornutum) 14 grown in hydroponic solutions. Simultaneous bioavailability 15 of iron (from NZVI) was also determined. Spent NZVI 16 particles (after phosphate adsorption) were added to the algae 17 and spinach growth media as the only source of phosphate and 18 iron. Phosphate sorbed by NZVI was bioavailable to both algae The concentration of algae increased by 6.7 times when the only source of phosphate was spent NZVI as compared 20 to algae grown in standard all nutrient media (including phosphate). Again, removing phosphate from the growth media 21 decreased the algae concentration ∼3 fold when compared to algae grown in all-nutrient media. In the spinach study, plant 22 biomass increased in the presence of spent NZVI (where nanoparticles were the only source of phosphate) by 2.2−4 times more 23 than the plant treated with the all-nutrient solution. Results also indicated 21, 11, and 7 times more iron content in the roots, 24 leaves, and stems of the spinach treated with spent NZVI, respectively, as compared to the controls.
