Abstract
A continuous, fast and economical high temperature synthesis of iron oxide nanoparticles was developed and compared to a conventional batch synthesis in terms of production costs.
Highlights
Among the various synthetic routes for the production of iron oxide nanoparticle (IONP), the most common ones are the aqueous co-precipitation method and thermal decomposition in organic solvents.[2,6,11,12]Co-precipitation synthesis is rather simple, as it uses relatively cheap and non-toxic chemicals, temperatures
The reactor was operated at varying flow rates, IONPs were synthesised at different mean residence times tr
The initial flow rate was set to 1.7 ml min−1 followed by 3.7 ml min−1, 2.7 ml min−1, the lowest flow rate of 0.7 ml min−1, and set back to 1.7 ml min−1 to test for reproducibility. This sequence of flow rates was chosen to ensure that any correlation between the residence time and the synthesis products cannot be assigned to any other temporal characteristic of the reactor operation
Summary
Among the various synthetic routes for the production of IONPs, the most common ones are the aqueous co-precipitation method and thermal decomposition in organic solvents.[2,6,11,12]. Co-precipitation synthesis is rather simple, as it uses relatively cheap and non-toxic chemicals, temperatures
