The invention relates to a method for purifying a bisphenol compound in a surface water sample extraction liquid and aims to solve the problem that the current analysis detection process of the bisphenol compound in the surface water sample extraction liquid is easily affected by a water matrix. The method comprises the steps that a composite chromatographic column is prepared, fillers of the composite chromatographic column comprise glass wool, anhydrous sodium sulfate, magnesiumtrisilicate, neutral silicone and anhydrous sodium sulfate sequentially from bottom to top, after the extraction liquid is added to a pre-leached chromatographic column, leaching is performed with a normal hexane and dichloromethane mixed solution, then eluting is performed with an acetone and dichloromethane solution, and a fully purified effect is finally realized. According to the method, the purifying treatment time can be shortened, the use amount of an elution solvent is reduced, and the cost is saved. The method is applied to the field of surface water sample purifying.

The invention provides a method for reducing nitrate radical in water to nitrite radical. The method is characterized in that a solution containing the nitrate radical is conveyed to a six-way valve after being absorbed by a peristaltic pump; the six-way valve is connected with a cadmium reduction column; and the nitrate radical in the solution is deoxidized to nitrite radical in the cadmium reduction column. The invention has the advantages that both the peristaltic pump and the six-way valve are controlled by a computer; via a compiled program, the peristaltic pump can be started or shut down, the speed of the pump can be changed, and a rotor of the six-way valve rotates, thereby realizing automatic control of reduction, cleaning and activation of the whole method; the cadmium reductioncolumn filled with cadmium filings has high reduction efficiency and long service life and is not influenced by water matrix. The cadmium reduction column has the advantages of simple manufacturing process, large contact area with a water sample, rapid, simple and convenient and efficient reduction process and the like.
