X-ray Photoelectron Spectroscopy Study of Double Comb Shape Copolymer on Atrazine Particles Surface
The electron state of adsorption of double comb shape copolymer on the surface of atrazine particles was observed with X-ray photoelectron spectroscopy and the adsorption layer thickness was also calculated.After the adsorption,the absorption strength of N 1s and Cl 2p on the interface of atrazine particles decreased sharply and the absorption peak of Cl 2s almost diminished.Because of the contribution of C and O in the dispersant,the absorption strength of C 1s and O 1s on the interface increased.Moreover,the dispersant formed an adsorption membrane coating the atrazine particles thoroughly,whose thickness is 14.98 nm.This report expands the application field of X-ray photoelectron spectroscopy and it also plays significant role in the theory of atrazine suspension concentrate stability.
