Hi Rashid,

If I reduce my volume then do i need to reduce nanoparticle concentration too ?

I Planned to do experiments with minimum 10 mg of nanoparticles in 100 ml distilled water. If I reduce the distilled water volume to 10 ml means what would be the nanoparticle concentration. Please let me know about the adsorbent concentration.

Thanks

Qammer Zaib

The experimental error (uncertainty) increases when you are working with small volumes.

Hi Qammer,

So shall i stick with 100 ml? What about using 50 ml? Please help me to figure out the exact quantity
