use | arsenic atomic absorption standard sample Chinese alias 2,3,4, 6-tetrachlorophenol, can be used as an intermediate in pharmaceutical synthesis. Chlorophenols are a kind of typical "three-causing (carcinogenic, teratogenic, mutagenic)" organic pollutants, which are widely used in the production of preservatives, dyes, herbicides and pesticides. |
detection | matrix dispersion-magnetic solid phase extraction enrichment and detection of trace chlorophenol pollutants in seawater using molecularly imprinted magnetic composites. remove 40mL of seawater sample solution and place it in a 150mL flat-bottomed flask, adjust the pH value of the solution to 3.0, add 20mg molecularly imprinted magnetic composite material, oscillate at 150 r/min minutes at 308K for 5min, magnetically separate, and pour out the upper layer solution. Then add 1 mL1%NaOH methanol solution swirl for 4min for desorption, magnetic separation, suck the supernatant, nitrogen blowing to dry, dissolved in 200 μL methanol, liquid chromatography analysis. The analysis conditions of liquid chromatography are: C18 reversed-phase liquid chromatography column (4.5mm × 250mm,5 μm); Mobile phase: A: acetonitrile solution; B:5mmol/L ammonium acetate aqueous solution; Gradient elution procedure: 0~5min,35% A ~ 90% A;5~7min,90% A;7~10min,90% A ~ 35% A;10~12min,35% a. Injection volume: 20 μL; Column temperature: 30 ℃. Ultraviolet detection wavelength: 254nm. |
