Content Summary | The sonochemical degradation of aqueous solutions containing low concentrations of six phthalate esters at an
ultrasonic frequency of 80 kHz has been investigated. Ultrasonic treatment was found capable of removing the four
higher molecular mass phthalates (di-n-butyl phthalate, butylbenzyl phthalate, di-(2-ethylhexyl) phthalate and di-noctyl
phthalate) within 30–60 min of irradiation. The rest (dimethyl phthalate and diethyl phthalate) were more recalcitrant
and nearly complete removal could be achieved only after prolonged irradiation times. The relative reactivity
of phthalates was explained in terms of their hydrophobicity. Experiments were carried out at an overall initial
phthalate concentration of 240 lg l1, values of electric power of 75 and 150 W, temperatures of 21 and 50 C and in the
presence of NaCl to study the effect of various operating conditions on degradation. Solid-phase microextraction
(SPME) coupled with GC–MS proved to be a powerful analytical tool to monitor the sonochemical degradation of
phthalate esters at low lg l1 concentration levels, minimising the risk of secondary contamination during sample
preparation, a major parameter to consider during phthalates analysis. The advantages as well as disadvantages of
using SPME are also highlighted. | en |
