Summary: | The influence factor for polystyrene based fluorescent particles' adsorption on Cu surface in liquid environment was investigated. The fluorescent particles with a size of 100 nm were used as the adsorbing particle for avoiding the disturbance to the adsorption result. The contrast between the fluorescent image and SEM image showed that there was a one‐to‐one correspondence between the fluorescent spot and the particle. This revealed the method of counting the fluorescent spot to obtain the adsorbing particle result is accurate. Zeta potential and ionic strength would affect the value of electrical double layer force. And the electrical double layer force and Van der Waals force between particles and surface determined the behavior of particles when particles got close to Cu surface. Results showed that particle adsorption on Cu surface was linear to the multiply of zeta potential for particles and Cu surface. Also, the influence of ionic strength on fluorescent particle adsorption was investigated. Finally, the quantitative description between zeta potential, ionic strength and particle adsorption was given. Copyright © 2013 John Wiley & Sons, Ltd. |
