Abstract
A determination method of phenols in water samples was developed. To optimize the conditions for direct acetylation of 16 phenols, absolute recoveries were measured. Alkylphenols, chlorophenols and nitrophenols were acetylated almost quantitatively with acetic anhydride using K2CO3 as base. Then, acetyl derivatives formed were quantitatively extracted with dichloromethane.
Linear working curves through the origin were obtained in the concentration range 0.05 to 5μg / L except nitrophenols.
