To test for good nanoparticle synthesis, you can

1. Separate them, wash, dry to constant weight, weigh and compare with the theoretical yield of the reaction product.

2. For a qualitative analysis, sodium chloride solution can be added. If a white precipitate of silver chloride appears, then there is an excess of silver ions.

Use icp after removing the nanoparticles and digesting the supernatant to eliminate citrate ions that will be chelating Ag+ ions.
