3.2.2 Dynamic Light Scattering
Dynamic light scattering (DLS) is a technique in physics that can be used to determine
the size distribution profile of small particles in suspension. In Fig. 3, the size of the
nanoparticle was more than the expected. The peak was formed at 279.2 d. nm
depicting the diameter of the synthesized TiO 2 . The PDI value was found to be
around 0.4511. In Fig. 4, the size of the particle increased to 372 d.nm, which was
no longer a nanoparticle (Figs. 2 and 5).
3.3 Dye Degradation
Dye in all the three samples was degraded in almost equal time showing that there
were no significant changes by altering the concentration of TiO 2 nanopowder. No
color change was observed in the control as it had no nanopowder. The color of
