Method for measuring surface oxalate in aluminum hydroxide produced by Bayer process

The invention belongs to the technical field of material analysis, and particularly relates to a method for determining oxalate on the surface of a solid phase. According to the method, the precipitation degree of sodium oxalate on the surface of aluminum hydroxide is judged in time by detecting the content of sodium oxalate on the surface of the total solid phase of aluminum hydroxide in the process of producing aluminum oxide by adopting a Bayer process and seed decomposition, a production organization method is adjusted, the content of sodium oxalate in a system is reduced through a specific method, and normal production is guaranteed. When the method is used for measuring the content of the oxalate on the surface of the aluminum hydroxide solid phase, the accuracy of the measuring result is high. The method for determining the oxalate on the solid phase surface of the aluminum hydroxide has important guiding significance for producing aluminum oxide from imported ore, stabilizing the production process an
