Nano silver dispersion has been widely used in various fields such as medical science, electronics, and food packaging. The higher the concentration of nano silver dispersion, the stronger the anti-bacterial properties. However, sometimes it is necessary to dilute the high concentration nano silver dispersion to a lower concentration. This article will guide you through the process of how to dilute high concentration nano silver dispersion to low concentration effectively.
Step 1: Prepare Deionized Water
Before diluting the high concentration nano silver dispersion, you need to prepare deionized water. Deionized water is preferred because it has fewer impurities, which can affect the properties of the nano silver dispersion. You can purchase deionized water or DIY it by using a deionization filter.
Step 2: Calculate the Volume
After the deionized water is ready, you need to calculate the volume of the final dispersion you want. For example, if you have 10ml of 1000 ppm (parts per million) nano silver dispersion and want to reduce it to 100 ppm, you need to calculate the volume of the deionized water required to dilute the nano silver dispersion.
Formula: V1C1 = V2C2
V1 – The volume of the nano silver dispersion you have (ml)
C1 – The concentration of the nano silver dispersion you have (ppm)
V2 – The final volume you want (ml)
C2 – The final concentration you want (ppm)
Using the formula, the volume of deionized water needed to dilute 10ml of 1000 ppm nano silver dispersion to 100 ppm would be:
V2 = (V1 x C1) / C2
V2 = (10 x 1000) / 100
V2 = 100ml
Step 3: Dilute the Nano Silver Dispersion
Once you know the volume of deionized water you require, you can start diluting the nano silver dispersion. First, pour the required volume of deionized water into a clean container. Then, add the high concentration nano silver dispersion into the container. Stir the mixture thoroughly until the nano silver dispersion is evenly distributed.
Step 4: Test the Final Concentration
After diluting the nano silver dispersion, you need to test the final concentration to make sure it is the desired concentration. Use a UV-visible spectrophotometer to test the final concentration. If the final concentration is not satisfactory, adjust the volume of the deionized water or the nano silver dispersion and repeat the process.
Conclusion
Diluting high concentration nano silver dispersion to a lower concentration is an easy and straightforward process. You only need to follow the steps mentioned above to ensure that the final concentration is the desired concentration. Remember to wear the right protective equipment such as gloves and goggles when working with high concentration nano silver dispersion.
