Abstract

The invention provides a device and a synthesis method for one-step synthesis of layered hydroxide using solid waste. The device includes a material acidolysis chamber, an ion precipitation chamber and an ion filter chamber. The material acidolysis chamber mainly includes a chemical reaction box, a magnetic stirring controller, a liquid drain hole and an acid injection hole; the ion precipitation chamber mainly includes a solution mixing box, an overflow hole, a liquid addition hole, an air inlet hole and a top cover , the ion precipitation chamber and the material acidolysis chamber are connected by channel-tenon assembly and bolt pre-tightening; the ion filtration chamber mainly includes a liquid inlet bin, a filtrate bin, a circulation bin, a sealing cover and a vacuum filtration device, and the filtrate bin is arranged The discharge pipe controls the liquid inlet valve by floating, so that the filtrate automatically enters the circulation chamber from the filtrate bin, and finally returns to the solution mixing box. The device and the synthesis method of the invention can simplify the operation process of using solid waste as raw material to prepare layered hydroxide, reduce the preparation cost of layered hydroxide, improve the preparation efficiency, and realize one-step synthesis of solid waste layered hydroxide.

Description

technical field [0001] The invention belongs to the field of resource utilization of solid waste (solid waste), and particularly relates to a device and a synthesis method for synthesizing layered hydroxide in one step by utilizing solid waste. Background technique [0002] Layered hydroxides are a class of compounds with a special intercalation structure, usually consisting of two layers of positively charged metal cations with a charge-balancing anion present in between. Due to the weak interaction between the interlayer anions and the layers, this type of compound exhibits strong adsorption to some special ions and functional groups, and is widely used in the fields of adsorption and catalysis due to its unique structure and properties. The synthetic preparation of layered hydroxides usually uses higher purity chemicals as raw materials, such as expensive soluble magnesium salts, aluminum salts or aluminum hydroxide is the main source of magnesium used to synthesize hydro...
