How to dilute nano silver dispersion from high concentration to low concentration? How much deionized water should be added?

Nano silver dispersion is an important nano material with various applications such as sterilization and anti-corrosion. When using this material, it is sometimes necessary to dilute the high concentration dispersion to obtain the desired low concentration. So how should dilution be carried out?

The key to diluting the nano silver dispersion is to add an appropriate amount of deionized water. Generally speaking, the proportion of water added can be calculated based on the target concentration and current concentration. If it is necessary to dilute 100 milliliters of a dispersion with a concentration of 1000 ppm to 100 ppm, then 900 milliliters of deionized water need to be added. That is to say, the desired volume of deionized water can be obtained by dividing the target concentration by the current concentration, subtracting 1, and multiplying it by the volume of the current dispersion.

It should be noted that sufficient stirring is required during the dilution process to ensure that the silver nanoparticles are uniformly dispersed in the solution. In addition, the diluted nano silver dispersion should be used as soon as possible and should not be left for a long time to avoid uneven concentration caused by the deposition of nanoparticles.

In addition, the dilution method may vary for nanosilver dispersions in different concentration ranges. When the concentration is high, more deionized water needs to be added to achieve the corresponding dilution ratio; When the concentration is low, the amount of water added can be appropriately reduced to avoid excessive dilution leading to poor results.

In summary, the key to diluting the nano silver dispersion lies in calculating the appropriate amount of water added and ensuring uniform stirring. In practical operation, adjustments should be made according to specific situations to achieve the best results.
