چکیده
|
The paper established a new resonance light scattering method for determining quercetin content in water solution. it was found that in hexamine buffer solution (ph7.50),sodium-dodecylbenzene- sulfonate-hexadecyl-trimethyl- ammonium-bromide system can enhance the resonance light scattering intensity of quercetin which is in proportion to the content of quercetin in the range of 2.0×10 -9 to 5.0×10 -5mol/l. the detection limit is 5.0×10 -10mol/l.
