METHOD FOR DETERMINATION OF INDOLE-ACETIC ACID Russian patent published in 1994 - IPC

FIELD: analytic chemistry. SUBSTANCE: method consists in extracting b-indoleacetic acid from analyzed sample with toluene solution of quaternary ammonium base in form of chloride ion containing from 30 to 60 carbon atoms within quaternary ammonium base concentration of 1·10^-4-1·10^-3 mole/l and pH of 7-9. Further, the analysis is carried by luminescent method with λ_exc = 280 nm, λ_lum = 350 nm, register intensity of luminescence of quaternary ammonium base solution. EFFECT: higher efficiency. 5 tbl
