[0002] Antimony is a widely distributed metalloid element that is toxic and potentially carcinogenic. Affected by human activities, antimony pollution in the environment has become increasingly serious. In the natural environment, antimony exists in two main oxidation states: trivalent antimony (Sb(III)) and pentavalent antimony (Sb(V)). Although Sb(III) and Sb(V) have different chemical properties and environmental behaviors, they can coexist in many cases. Currently, there are few methods that can separate them simply and efficiently. Most research on the control of antimony pollution focuses on pentavalent antimony, while research on trivalent antimony is still insufficient. In addition, due to redox reactions, the content of trivalent and pentavalent antimony is lost in the process of sample solutions from the field to the laboratory.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Resin activation can be achieved by cleaning the SCX column with sulfuric acid and ultrapure water. Since the filling material in the SCX column is a benzenesulfonic acid-based filler on a silica gel matrix, the sulfonic acid group (-SO3H) of the resin is highly ionized in the acid (R-SO3) and will be used for complete deionization in the form of hydrogen. The applicant has demonstrated through experiments that 10% sulfuric acid has the best activation effect, and the optimal activation time is two hours. The applicant used ultrapure water, 10% sulfuric acid, and 10% acetic acid as activators, respectively. The comparative test results are shown in the table below:

[0021]

[0022] As can be seen from the table above, the Sb(III) recovery rate meets ≥95%, which mainly affects the Sb(V) recovery rate. The effect of 10% sulfuric acid is greater than that of ultrapure water, so 10% sulfuric acid activated resin column is selected.

[0023] The sample solution is introduced into the SCX chromatographic column through diafiltration, and the filtrate of the SCX chromatographic column is collected and rinsed with ultrapure water. The rinse liquid and the filtrate are collected together to form the separation liquid of pentavalent antimony; trivalent antimony is eluted with hydrochloric acid to facilitate the separation of trivalent antimony and pentavalent antimony;

[0024] 2. By setting up a displacement mechanism, a clamping mechanism and a brushing mechanism, the SCX chromatographic column is placed on the inner wall of the rotating seat, the rotating ring is rotated to clamp the SCX chromatographic column in the rotating seat, and the motor is started to drive the movable rod to displace, drive the SCX chromatographic column to move, and the SCX chromatographic column automatically rotates when it is displaced; the nozzle sprays liquid to clean the SCX chromatographic column. After cleaning, the brush cover is inserted into the SCX chromatographic column, and the SCX chromatographic column continues to move. The brush cover moves synchronously with the SCX chromatographic column, and the SCX chromatographic column rotates automatically. The brush cover brushes the SCX chromatographic column, which is convenient for cleaning the SCX chromatographic column. BRIEF DESCRIPTION OF THE DRAWINGS
