Hydroxyproline after chloramine T oxidation, and on-dimethylaminobenzaldehyde The reaction to form a red compound, at a wavelength of 558nm at the colorimetric determination.

4 Reagents

Unless otherwise specified, the reagents were of analytical grade. Water is distilled or deionized water, or the same purity water. Measure 750mL of water in a 2L volumetric flask, was added slowly with stirring 320mL of concentrated sulfuric acid (ρ20 = 1.84g/mL). Cool to Room temperature water volume. Comprising the following components. a) 26.0g of citric acid monohydrate (C6H8O7 · H2O); b) 14.0g of sodium hydroxide; c) 78.0g of anhydrous sodium acetate [Na (CH3CO2)]. With 500mL of water and dissolving the reagent into the 1L flask, was added 250mL n-propanol, water volume. The solution was dark at 4 ℃ stable for several weeks. 4.3 chloramine-T solution Weigh 1.41g trihydrate · N- chloro - toluene sulfonamide sodium salt (chloramine T), by 100mL of buffer solution (4.2) was dissolved.
