my zinc acetate solution in dionised water(20 ml) gels by adding just a drop of the complexing agent diethalonamine (DEA) to it in order to release the Zn+2 ions and this phenomenon manifests when I use high concentrations of zinc acetate (greater than 1M ), what does this gel mean?knowing that I do not know the concentration of the complexant that I use!
but at small concentrations (less than 0.4 M) I don't have this problem.
Dear Farid Dris, complexing agents are used to controle the kinetics and growth of nanoparticles. When the precursor concentration is increased, the role of the complexing agent is reduced and limited. This leads to fast and random growth and agregation, which looks like a bulky gel mass is formed. Please have a look at the following documents. My Regards
