What is the proper speed of stirrer (in rpm) during the synthesis of nanoparticles from iron salts (Fe II and FeIII) in presence of alkali by coprecipitation method?
Hey
as i can't send PM's ( don't know why ) so i'm going to answer to your PM's question here.
if you are working with small volume ( 100ml) the suitable stirring speed it's between 250~300 rpm ( you can use a high speed i don't think it's a problem but you are going to get the iron particle everywhere and it's too hard to remove them) , at the end if there is some agglomeration of the iron particle then you can use magnetic field to remove them .
