Abstract

The invention provides a silicon oxynitride chromatographic stationary phase material and a preparation method thereof. The silicon oxynitride chromatographic stationary phase material containing silicon-ammonia groups and imido group on a surface is prepared by undergoing a nitridation reaction on ammonia gas and silanol of a silicon oxide material serving as a raw material at a high temperature. The nitrogen content of the prepared silicon oxynitride material can be controlled by controlling the flow rate, nitridation speed and nitridation time of ammonia gas. The silicon oxynitride material prepared with the method can well keep the shape, pore canal structure and specific surface area of the silicon oxide raw material. The silicon oxynitride material prepared with the method has high chemical stability, can exist stably in a mobile phase of which the pH is 1-13 without losing, and has a wide application prospect when taken as a chromatographic stationary phase material and a solid phase extracting material. The preparation method is easy to operate, has low production cost, and is suitable for industrial production.
