Effect of synthesis parameters on the particle size of the zero valent iron particles

ABSTRACT

It is known that synthesis conditions significantly affect the particle size. The sizes of particles also affect the particles efficiency. In this study, because of its importance as a material, the effect of synthesis parameters on the particle size of zero valent iron particles such as initial ferric iron concentration, initial borohydride concentration, initial stabilizer concentration, temperature, initial pH, NaBH₄ adding rate, and stirring rate were examined in detail. The results showed that the initial ferric iron and borohydride concentrations used in the synthesis primarily affected the particles sizes of zero valent iron. Also high temperature values showed a negative effect in producing small particles.
