Device and method for analyzing lithium-rich adsorbent

The invention provides a device and method for analyzing a lithium-rich adsorbent, and belongs to the technical field of salt lake lithium extraction. An analysis liquid storage tank is communicated with a first buffer tank in a plurality of buffer tanks which are communicated in sequence, and the last buffer tank in the plurality of buffer tanks which are communicated in sequence is communicated with a lithium-rich analysis liquid tank; the outer wall of each buffer groove is wrapped with a heating device used for heating the buffer groove. Each buffer tank is communicated with an adsorption column assembly; the adsorption column assembly consists of a plurality of adsorption columns which are communicated in sequence; wherein the feeding end of the first adsorption column in the same adsorption column assembly is communicated with the buffer groove, and the discharging end of the last adsorption column in the same adsorption column assembly is communicated with the same buffer groove.
