Ultraviolet labeling technology was used to enhance the ultraviolet absorption of polycarboxylate, and then the technology of ultraviolet absorption spectrum and total organic carbon analysis is used together to effectively distinguish respective adsorption behavior of polycarboxylate and quaternary ammonium salt cation molecules when they exist at the same time, and the interaction between three typical quaternary ammonium salt cations and polycarboxylate in cement montmorillonite system is studied systematically. The results show that the adsorption of polycarboxylate on the cement surface is not affected by the small molecular quaternary ammonium salt, the Gemini quaternary ammonium salt can promote the adsorption of polycarboxylate, the polymer quaternary ammonium salt can inhibit the adsorption of polycarboxylate water reducer on the cement surface. And the three quaternary ammonium salts can effectively inhibit the adsorption of polycarboxylate water reducer on the surface of montmorillonite when doped as 2.5×10-4. The effect of Gemini quaternary ammonium salt and polymer quaternary ammonium salt is more obvious. The inhibition effect of Gemini quaternary ammonium salt is stronger at low dosage, while the inhibition effect of polymer quaternary ammonium salt at high dosage is better.
